Customer Question

I have a 15k unit. There is a problem with the starter ignition. The relay clicks on/off quickly then repeats when trying to start and all 4 reds start flashing. Voltage to starter wire (blue) varies 1 to 9 volts . Checked starter ok. Battery voltage 13 volts. It may be a relay or circuit problem. Please Advise

Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!

Does the battery voltage drop at all when you engage start? Typically there is no relay between starter switch and starter solenoid, and the low voltage is the reason the solenoid is not closing.

Customer: replied 5 months ago.
No drop there, but I checked the Generac starter contactor relay power supply voltage to wire 56 and have low voltage same as the starter fire wire.
Expert:  Curtis B. replied 5 months ago.

So you need a new relay.

Customer: replied 5 months ago.
No the voltage coming to the relay is bad. This unit has a circuit board for ignition.
Customer: replied 5 months ago.
Voltage is available but too low and sporadic when starting. It has an automatic ignition and manual ignition switch connected to a circuit board.
Expert:  Curtis B. replied 5 months ago.

If you have 12 volts to the relay on the power side, to solenoid, and t has little output, the relay is not passing the voltage, take a jumper wire bypassing the relay and see if the starter engages.

the starter is fine when this is done
Expert:  Curtis B. replied 5 months ago.

Replace the relay!

Customer: replied 5 months ago.
the voltagecoming to the relay is low
Customer: replied 5 months ago.
the circuit board has 4 red flashing lights
Expert:  Curtis B. replied 5 months ago.

OK< I had asked if voltage was good to the relay, so it is not, trace the wires back, the flashing lights are showing low voltage, where is battery voltage lost?

Customer: replied 5 months ago.
Not sure, but suspect the ignition control circuit board. It clicks on and off while a manual start switch is applied. Voltage is low and varies with each click.
Expert:  Curtis B. replied 5 months ago.

Do you have 12 volts to it?

Customer: replied 5 months ago.
Probably, but not sure how to check it.
Expert:  Curtis B. replied 5 months ago.

probe the wires , it has to have power wire from battery source, and low voltage may be from a bad fuse or fuse holder not passing full battery voltage to the control.

Customer: replied 5 months ago.
checked voltage around fuses and was 13.8 volts
Expert:  Curtis B. replied 5 months ago.

OK< let me opt out, maybe someone else can figure it out. Sorry. Please do not respond to me or it locks the question to me.
