Generator blowing fuses
Okay, I'm not very experienced with generators since this is my first one, but I have an Onan 4000 watt Microquiet, mounted in my Class C. It's about 8 years old now. I don't use it often, so I fire...

I hope you ment 12.5 fuse. 125Amps for a DC control fuse is a bit much. Which shop did you go to here in Texas. Sounds to me that you have a bad starter. Very common problem on the KY units. The bendix falls apart jamming up the starter. Not hard to change,just a pain to get to.You have to remove it from the RV. Then remove the cover. To get to the starter.
No, it's really a 125 amp. It's in line with the main battery cable, so it's not just for the generator, it apparently protects the battery and associated cables. This is the one that's blowing. The starter seems okay (to me, at least), and cranks very smoothly until it blows the fuse. When I try to start it the third time, it sounds like the battery is low, and I'm wondering if that would cause the generator starter to try and draw more power for starting. This last time I plugged into shore power for about an hour, after which the generator started. I don't know if it was because there was now more power available in the battery, or if it had enough of a prime to start.
