Powermate Generator Troubleshooting


To troubleshoot any generator, the best action plan is to find the best possible cause of the fault. When we talk about Powermate Generators, the common issues include the contamination of muffler, capacitor problems, and the unstable engine speed.

The engine won’t run. The possible cause of starting problem can be due to spark plug itself or its connections. Muffler corrupted with external debris can also be one of the reasons along with the lower levels of gas.

High Voltage in No-load condition. The primary reason might be the use of high capacity capacitor or the speed of engine-motor is set too high.

Low Voltage in No-Load condition. The possible causes include low-capacity capacitor is in place, motor RPM is too low or rotary diodes are faulty.

Erratic Voltage. The reasons behind unstable voltage include unsteady engine RPM or loose connections.

Powermate Generator DIY Repair


The faults mentioned above can be resolved by taking easy steps before calling any of the authorized service centers. For engine start-up problems, you need to clean the debris from the exhaust of muffler. Check and tighten the spark plug wire and fill the tank with a necessary quantity of gas.

In the case of high voltage scenario, you can get rid of the problem by adjusting the RPM of the engine. Check and replace the capacitor with desired capacity. If you are facing with low voltage, you need to adjust the RPM of the engine, check the capacitor rating and replace it, if necessary and change the faulty rotary diodes.

For unstable voltage, it’s a good idea to check the RPM of the engine or otherwise check and fix any loose connections.

    Hello. I certainly hope you can help me. I have an older Coleman ProGen 6500 portable generator model PM0536503.17, serial number 86890305, that is having running problems. It has a Subaru EH41D 13.5HP engine (EH410YD2410) and is using a “DC-Solenoid Shindengen size 100s pull” solenoid for speed control. The generator will idle properly but as soon as an electrical plug is inserted the engine jumps to max rpms. I am guessing the problem is either the solenoid or the idle control module. I have searched the internet for a replacement and haven’t been able to find anything about this particular solenoid and very little about the idle control module. From your experience can you give me your best guess as what the problem is and if there is a suitable replacement available and where I might obtain one. I can send you a photo of the solenoid and/or the control module if that would help. Thanks so much for your help. Gerald Bechtel
