Planning to ignore the weird noises from our Generac 7.5kW diesel generator backfired when my wife pointed out I definitely made things worse during my repair attempt. I have a 2007 Monaco with a Generac 7.5kW diesel generator, and yesterday when I tried starting it, the battery was really weak. I probably held the starter button too long - maybe 15 seconds or so - because it was cranking so slowly and I kept hoping it would catch.

Now when I try to start it, I just get a single click and nothing happens. I'm worried I damaged something by cranking it so long with that weak battery. Should I be looking at the starter solenoid or starter motor? Is there anything I can check myself before I have to take it to a repair shop? I'd really appreciate any guidance on troubleshooting this. …more

Generac generator in my 2003 Dutch Star needs a specific coolant hose — part number C4845 — and it's been discontinued everywhere I look. Called six RV parts suppliers and checked every online dealer. Need to find a compatible replacement before this thing overheats on our summer trip. …more

Found that ever since those heavy rains last month hit, my 2007 Alfa's Generac 7.5kw diesel generator shuts down exactly 2 minutes after firing up the basement AC.

Just did a full service (oil, filters, the works) so it's not basic maintenance stuff. I can restart it right after it shuts off, but if the AC is still calling for power, it dies immediately again. No error codes or blinking lights to give me a clue.

Is this a fuel delivery issue where it can't keep up with the AC load? Or am I looking at something else entirely? Really hoping someone's dealt with this exact same 2-minute thing before! …more

Looked like a simple breather hose replacement on my Generac RV generator, but ever since I finished the job, oil has been leaking everywhere. I replaced the cracked original-style breather hose with a new version that now includes an elbow and short extension inside the air filter housing. While the hose replacement definitely helped reduce the oil drip, I'm still seeing some persistent leakage underneath the unit.

The new hose design appears to be an upgrade from Generac, with the uphill extension meant to help oil sucked from the crankcase run back down into the engine. I'm hoping this will further minimize the drip issue. I want to make sure I'm not missing something obvious before I take it to a repair shop. Has anyone else experienced similar issues with their Generac generator's breather tube? Any guidance on troubleshooting would be really appreciated. …more
