Please call us at for more information. Ensure that if your original installation had one, that you fit it with your replacement starter. Failing to fit the spacer will cause the starter to remain engaged into the flywheel ring gear. This will seriously damage the starter. Left Hand Engine Rotation This is the most common engine rotation found on today’s marine engines. Same rotation as automotive engines. Use these drawings to determine the correct starter rotation needed.

Starter Motor Wiring

The conductors used to carry this amount of current battery cables must be large enough to handle the current with very little voltage drop. It would be impractical to place a conductor of this size into the wiring harness to the ignition switch. To provide control of the high current, all starting systems contain some type of magnetic switch.

There are two basic types of magnetic switches used:

Wiring Instructions for Magnetic Starters IMPORTANT If the compressor has a factory mount-ed magnetic starter, the starter has Use the wiring diagrams on the back of this sheet to install and connect power wires for the starter Starter Motor Connect power to the magnetic starter through the knock-out plug in the top.

The solenoid is an electromagnet that pulls an iron rod core into itself when energized. The rod is connected to an electric switch that turns on the starter motor. The rod is also mechanically connected to a spring loaded lever to push the starter motor pinion gear into the ring gear of the fly wheel, thereby connecting the starter motor to the engine. When the ignition switch is released from “start”, no electricity flows to the solenoid and the spring pulls the pinion gear back from the ring gear preventing it from grinding when the engine starts.

The solenoid does a lot of work and therefore demands a lot of voltage and current to work properly. A common problem with Z ignitions is that not enough voltage is received by the starter solenoid to pull the lever, so the starter is not turned on and the pinion gear does not contact the fly wheel ring gear. Only a “click” can be heard as the solenoid jumps but fails to pull the lever all the way. This is because voltage through the ignition start circuit drops too much on the long trip from the battery through a small gage wire to the fuse block, across two buss fuse contacts, through thin wires to the ignition switch, across dirty and worn contacts in the ignition switch, and out a thin wire to the starter solenoid.

Making matters worse, there is a huge drop in battery voltage when the starter motor tries to kick in. Several of the Zs I have owned experienced the problem of only clicking when the ignition switch is turned. This article shows a way to provide a improved voltage and current to a starter solenoid for a reliable and strong start. Below is a picture showing an inelegant, but functional, arrangement of a relay circuit that vastly improved starting in my Z.

Starter turns when hooking up battery (key not in ignition)

I believe this covers pretty much all air-cooled Volkswagens I know for a fact it applies to late Buses with Type 4 engine , early Vanagons with Type 4 engine , Beetles, and Karmann Ghias. Removing the starter is a fairly simple task. The first step is to disconnect the ground strap from the battery.

The single-phase induction motor can be made to be self-starting in numerous ways. One often-used method is the Split Phase motors. Another method is the Capacitor Start Induction Run Motors.

I have three posts, two small posts and one large post on my starter solenoid… Typically, GM vehicles prior to have starter solenoids with three posts: Battery — This is the large post on the solenoid which is usually found on the center top of the solenoid. This is the post where the positive battery cable attaches along with any battery feed wires that the car might require.

These wires are usually heavy gauge red, or black wires and may contain a fusible link. This post becomes hot only while the starter is cranking. On an original points car, this post feeds a wire that sends full voltage to the coil during cranking. This wire is know as the resistance bypass wire, as it bypasses the resistance circuit that will typically feed the coil when the car is running. This is done to boost the coil output during engine start. It is noteworthy that on some of our HEI conversion engine harnesses this wire is retained due to the design of the factory ignition switch and circuitry.

While factory HEI vehicles do not have this bypass wire, on some of our HEI conversion harnesses, this wire is still required and may be found on your harness. This wire is typically yellow, but can be green, pink, or black with a pink or yellow stripe. On typical GM starters this post is generally the small post closest to the engine block.

This post will accept the purple wire on the engine harness. The purple wire carries current from the ignition switch, often via the neutral safety switch, down to the starter to activate the starter.

How to Replace a Starter Motor

Page 2 Bench testing the starter is the most effective way to find out if the starter motor is in fact BAD. This is an OFF Car test. So you’ll need to remove the starter motor from the car or truck to bench test it. It’s a very easy test to do. The hardest part is removing the starter motor.

How Does a Starter Motor Work? However, getting it to crank is actually much more involved than you might think. It requires a flow of air into the engine, which can only be achieved by creating suction the engine does this when it turns over. The starter motor is responsible for turning the engine over during ignition and allowing everything else to happen. How your starter works Your starter is really an electric motor.

On the engine, a flexplate or flywheel, with a ring gear around the edge, is attached to the end of the crankshaft. When you turn the ignition switch, the starter motor is energized, and the electromagnet inside the body engages.

Motor starting capacitor

I have fitted one of the new geared starter motors which only have two terminals – one on the starter for all the brown wires and one only on the solenoid. I am using the original loom which I assume has a built in resistor. Would appreciate advice as to correct connection procedure. This terminal is isolated from everything else when the starter is not active, and connected to 12V when it is.

How to hook up an electric motor start or run capacitor: Green links show where you are. Never work on live electrical equipment. Also A fractional horsepower electrical motor should show different electrical resistance between the three terminals Start, Run, and Common as we illustrate just below. Find the two highest resistance terminals.

The third one will be the common terminal. Our example is for a Frigidaire compressor motor. Electric Motor run speed side note: Incidentally while most electric motors are marked with a data tag indicating the motor run speed in RPMs it’s worth noting that the number of run coils is what determines the run speed of the motor.


A Chrysler gear-reduction starter cranks a V8 engine Problems playing this file? In , Chrysler introduced a starter incorporating a geartrain between the motor and the drive shaft. The motor shaft included integrally cut gear teeth forming a pinion that meshes with a larger adjacent driven gear to provide a gear reduction ratio of 3.

This permitted the use of a higher-speed, lower-current, lighter and more compact motor assembly while increasing cranking torque. It makes a unique, distinct sound when cranking the engine, which led to it being nicknamed the “Highland Park Hummingbird”—a reference to Chrysler’s headquarters in Highland Park, Michigan.

type of starter has a compact, high-speed motor and a set of reduction gears. While the motor is smaller and weighs less than conventional starting motors, it operates at higher speed.

Starter Motor Replacement How to Replace a Starter Motor Easy step by step guide on how to replace a starter and solenoid, though appearances may vary, the process is the similar for most vehicles. Negative Battery Terminal Removal Step 2 – After the battery has been disconnected, remove all access shielding and covering to expose the starter terminals on the solenoid. Some starters may not have this. Removing Starter Terminal Cover Step 3 – Exposing these terminals will allow access to loosen and remove the battery cable and trigger wire, note the position of the wires on the solenoid.

Starter Terminal Step 4 – After the terminals have been exposed, use a small socket or wrench to remove the starter solenoid trigger wire. Next two steps can be done after the starter has been unbolted. Remove Starter Trigger Wire Step 5 – Next, use a slightly larger socket or wrench to remove the positive battery cable. The starter will become free from the bell housing, it weighs a few pounds. Removing Starter Mounting Bolts Step 7 – After removing the starter motor mounting bolts, grasp the starter and remove it from the bell housing area, take this opportunity to inspect the flywheel gear condition.

Remove Starter Step 8 – Once the old starter has been removed, match the replacement unit to ensure a proper installation. New Starter Step 9 – After cleaning the mounting surfaces thoroughly, gently install the starter motor.


You turn the key to start, and you get nothing. This procedure is only for those times when the starter doesn’t even try to crank the engine. You turn the key and you get nothing or maybe a click and some dimming of the idiot lights. Here’s a troubleshooting procedure for you. Turn your headlights on and see how bright they are.

A starter motor is a basic electric motor with a few peculiarities that we should ex-plain. Mounted to the top of the starter motor is a small The above illustration demonstrates the routing order of the various wires that comprise the starter system. This wiring schematic includes the use of a hard start relay. Please refer to the upper.

Starter Problem Troubleshooting Starter Problem Troubleshooting One of our customers is having problems with intermittent operation of his starter. I thought that this might be of interest to others:. Troubleshooting a problem involves: The starter system on the functions as follows: The starter should spin the engine. If the starter doesn’t spin, we can split the system by assuming either: Turn on the interior lights and hit the starter switch.

If the interior lights do not dim at all when you hit the starter switch, but the starter doesn’t operate, you probably aren’t energizing the starter solenoid. Suspect the ignition switch, starter relay, transmission safety switch auto only – provides a ground for the starter relay , starter solenoid, or wiring between these devices.

If the interior light go very dim or go out when you hit the starter, you are probably energizing the starter solenoid, but there is not sufficient power to operate the starter motor. Suspect the battery cables or the battery.
