I have a 5FGC15. The lights for the air cleaner and the charging lights are staying on all the time. I tracedthe wires from the vacuum switch to the dash and those wires are good. I at a loss as to reason why that light stays on.. On the charging light I checked voltage when unit is running and at idle it is only putting out 12.2 volts but when you rev it up the voltage will climb to 13.8 volts>. I checked the crank volts of battery and it is good. Any help is very much appreciated
