A powerhorse 9000 generator the electric starter will not crank with the key. have replaced the solenoid . Can also jump the solenoid and the starter cranks. Is there a fuse on the starter circuit?

I'm sorry to hear that you're having trouble with your Powerhorse 9000ES generator. While I don't have specific information on the wiring of that particular generator model, I can provide some general guidance.

Typically, a generator's battery is connected to the starter motor and the electrical system. The positive wire from the battery is usually connected to the starter motor or the starter solenoid, while the negative wire is connected to the generator's chassis or grounding point.

As for the additional brown wire that changes to black and has an eyelet, it's difficult to determine its exact purpose without more information. However, it's possible that this wire is intended for a specific accessory or component of the generator. It may be a ground wire, a wire for a charging system, or a connection for a specific electrical component.

To ensure proper and safe installation, I recommend consulting the Powerhorse 9000ES generator's manual or contacting the manufacturer's customer support for detailed wiring instructions. They should be able to provide you with the specific information you need to properly connect the battery and any other wiring components.

This sounds like the starter solenoid isn't getting enough power. Jumping the solenoid is you simply bypassing it. Go back to basics. I may suggest things here you have already done but it helps to treat this as a simple check list.
- Check the fuse, sometimes the fix is that easy.
- Check the relay for the starter motor. It should click when the key is turned sending power to the solenoid.
- Check the voltage supply at the small wires at the solenoid. Using a multi meter set to DC Volts you should get around 12 volts when you turn the key. You might need a helper to do this.

Check fuse and connections between start switch, control board, and starter solenoid.



ENGINE CONTROLLER CIRCUIT BOARD
GENERAL:
The engine controller board is responsible for crank-
ing, startup, running and shutdown operations. The
board interconnects with other components of the DC
control system to turn them on and off at the proper
times. It is powered by fused 12 VDC power from the

Do you know what a wiring diagram is ? How to use a DMM - digital multi-meter to diagnose automotive electrical circuit's ? Looking at a wiring diagram to see what all is involved in the starter circuit , main battery cables , park neutral safety switch , starter relay etc.. Find video's on youtube . Do you have a manual or automatic trans. ? The purple wire get's B+ voltage from the starter relay in the underhood fuse / relay box .

The click will be the fuel switch on the carb that opens when the ignition is switched on. When you jumped the battery to the starter did you have the ignition on? If not it won't be getting fuel. If you find the wire that goes from the ignition switch to the starter solenoid (usually mounted on or near the starter motor) and connect the switch end of this to the battery does this crank the engine over? If so then the ignition switch will probably be faulty or have dirty contacts. If not then I'd suspect the starter solenoid.

You are saying that the starter motor is not working, that the engine is not cranking over, even with a boost?

If so, then either there is a problem in the starting circuit between the ignition switch and the starter, or the starter is bad. There is a way to check the starter on the vehicle: the starter will have 2 electrical connections. One is the positive battery cable, and the other is a small wire connection to the starter solenoid, mounted on the starter. The key should be off, the brake set, and the transmission in park or neutral. Use a small jumper wire or a small screwdriver, and jump the battery cable connection to the solenoid connector. Take off the solenoid electrical connector if you need room to do this. With key off, the engine won't fire and run, but if the starter is good, then jumping those two connections will make the starter engage and spin the engine over. (Of course, if key is in ON, the engine should start and run.) But you are just checking starter operation, so keep the key off. If starter is good it will crank the engine over. If jumping the two connections causes nothing, then it is pretty certain the starter motor or the solenoid is bad, and you need to replace it. (Take off the negative battery cable from the battery first to remove the starter from the vehicle.)

If jumping the starter caused it to operate, the starter and solenoid are good, and there is, again, a problem in the start circuit from the ignition switch to the starter solenoid. It could be simple like an electrical connection (like the one right there on the solenoid), or a component in the circuit between the ignition switch and the starter solenoid, like the neutral safety switch for example. You will need a wiring diagram and a multi-meter to diagnose further. Good luck, and hope you find the problem. Are you sure your battery is still charged up good?

first jump the starter to see if starter works

Hi government32, seeing how you just installed a new battery I'll assume you cleaned all the connections. Not cranking at all sounds like 3 possibilities, Key switch, starter solenoid, or starter. Lets check starter first. Using a jumper cable, jump from positive battery post to starter motor (you'll see the connection on the motor where cable is connected,thats where you hook jumper), if it cranks the starter motor is ok. If it doesn't thats the problem. If it does crank check the starter solenoid, using a jumper cable jump across from side to side (the 2 big terminals). If it cranks now the solenoid is bad or the electrical connections are dirty. There are also 1 or 2 small connections on solenoid from the key switch, make sure they are clean. If these 2 components check out the key switch is bad or the connections on it are dirty. (its usually not the switch).Hope this helps you.

Bad solenoid i would guess. Not making a connection there. Any basic wiring and ignition switch problems should be alleviated by jumping the starter with a screwdriver. I would check the solenoid and starter brushes

check fuel pressure.if not above recomended spec. replace fuel pump. for starting have solenoid 0n starter checked.
