Re: Generac Guardian air cooled does not crank

First off, a shout-out to Chris who shipped the much needed battery cable basically within one hour of the on-line order!!! The main issue was the red cable that goes from the battery to the starter motor. It was not that obvious that the cable was the culprit because I could measure 12V between the...

Re: Generac Guardian air cooled does not crank

That is the SCR. I am referring to the SC / Starter motor block. I think the SC is shut while the starter motor still works. Do you sell just the SC? Probably this one: https://shop.gentekpower.com/products/g ... 137d&_ss=r?

Re: Generac Guardian air cooled does not crank

Cool, thanks for the advice. I did what you suggested and the fan does rotate. I need to retest the SC one more time, as there are around +12V on wire 16 when I press the manual button but the Starter does not spin. The Starter worked when I bench tested it. So it is possible the the SC is dead. Cou...

Re: Generac Guardian air cooled does not crank

@Chris, as you suggested in another thread, removing the Starter Contactor and the Starter is a blind job. It also requires the hands of a fairy and the strength of Andre the Giant... I did it and bench-tested the starter motor, which works. Here are the bad news. I reached where the engine flying w...

Re: RPM Sensor Loss - Model 0056100

I have a 20kw air cooled Generac with v-twins engine. I can barely see the starter contactor buried in the back of the unit.

Re: RPM Sensor Loss - Model 0056100

Did you have to remove the back panel of the unit in order to remove the Starter Contactor? It does not looks like the Starter Contactor is easily accessible from the top. Thanks.

Re: Generac Guardian air cooled does not crank

@Chris, thanks for the info. @MacL, thank you for your concerns. Of course I have cleared the error fault and tried to start the generator again not just once but few times. I have load tested the battery too, as mentioned previously. I don't think reading the manual to understand where the various ...

Generac Guardian air cooled does not crank

I have a Generac Guardian 20Kw G0067290 with Evolution Control Panel. I got the error code 1505 RPM Sense Loss, so I load tested the battery, which was already 5 years old, and sure enough it was bad. I replaced the battery with a new one. Same error code and it is still not cranking. As I am a big ...

Broken battery connectors

I have a model 6729 20KW Guardian Series and one of the clamps (the one with the bolt and the nut) attached to the cables that connect to the battery is cracked and about to break. Is there a replacement part for the cables that connect to the battery or is there a way to repair the clamp? Any sugge...
