Bad computer ground?? 1991 454 motor home Class A
I grounded out my alternator wire (by accident!!) on my 1991 GMC 454 motor home while it was running. Stopped it dead. Now barely runs; won't idle, rpms up and down as you feather the throttle just to keep it running. Even though it was the hot wire, I'm guessing I compromised a ground and the engine computer is all over the place. Any ideas? Had just installed rebuilt engine, and even though running fine, it would randomly stall after about 45 min of idle. after shorting out hot wire; everything is bad...
