Generator repair
#1
Does anyone have a good source for repairing the electrical side of a
Briggs&Stratton 7500 watt gas generator? I have already talked to J&J Lucas, and Garden Exchange. I have returned to Home Depot who referred me back to the manufacturer. The manufacturer seems to sell parts but is no help on service and repair. Their authorized service providers do not work on the electrical side. Next time, I will buy the Honda without worrying about the price issue. Thank you for your consideration.

I recommend finding an auto repair center that says they know how to repair an alternator.


Rewiring an alternator is a common task, at least where labor is cheap and they are simply not tossed in the bin, and they should know.

symptoms? model number? are you handy with an ohm meter? usually not worth the labor to fix - is the downside to taking these units in for service....

sears repair center may be able to help, their mechanics are sharp.

There is an electrical motor and starter repair company in Hilo, between the airport and Walmart. Can't recall the name, but they have a truck parked outside with a sign in the back of the truck.

Been there, done that; all the repair places told me to just throw it away and buy another, it's all cheap Chinese crap because people aren't willing to pay for quality anymore.

Best bet for DIY is to find a similar genset with a blown engine and salvage the generator head from that. All commodity gas gensets spin at 3600rpm, so it'll "just work" as long as the pieces can be made to fit.

If you have access to one, best to put a multimeter on it and see what current/voltage you're getting. A lot of time, a blown capacitor is to blame - check the manual for location. For my genny, it is under the cover for the alternator. Unbolt the cover and check for cracks or other damage on the capacitor. If damaged, unclip it and bring it to JJ Lucas for a new one, ~$10. Cheap and easy fix.
YMMV

Good idea Iron. Better yet assume it is the capacitor.

I just took my Honda apart for third time to replace starter cord. I found a great on-line help discussion and have that saved to my computer.

So do some google searches with name and key words

Too late to matter now but generally if you can figure out what is wrong with a lot of stuff you can pull the part and if you can find a number on it you can, with some effort, find an inexpensive replacement part. I find that true of many things that would otherwise not be worth the repair cost, if taken in to a shop. An at least mid grade multimeter is a must for any household, IMHO.
