Generac Starting Problem
My Coach has a Generac Diesel Generator. It barely starts, even with a full charge of the house batteries and plugged into shore power. If the batteries are down a bit, then I have to use a jump start from my Toad to get it going. I measured the voltage right at the starter solenoid and it is 13.4 volts not under load. As soon as I push the start button, the voltage drops to 7.8 volts and the starter barely will turn. I found that the heavy size #2 battery feed cable does not come directly from the house battery bank. From the battery bank, it goes to the 12V Distribution panel, to one side of the battery boost relay, then through the Battery Disconnect Relay, then through a 150 amp circuit breaker, then to a terminal......and then it runs about 30 feet to the Diesel starter solenoid through the #2 cable. I have measured the resistance of all the possible places that I could be loosing the 6 volts under load and found no suspects.
Anyone had a similar problem and found a solution? Rook
