Turn ignition on, disconnect the grey wire at the buzzer, if it keeps buzzin the buzzer is shot.
If it stops buzzin, reconnect the grey wire and disconnect the temp switch on the port side head, between sparkplugs, if buzzin stops its the temp switch.
Disconnect the oil tank wire harness, check for same.
Ditto the fuel pump vac switch.
If the buzzer is OK its goin to be in one of the sensors or its wiring.
All the sensors are routed through the signal wire to the buzzer and isolated from each other by diodes. Temp switch is routed through the power pack, if it runs like crap I'd be testing the power pack.
The beeping is coded too, is it continuous beep or on off on off ?
Is there oil in the VRO tank?
If you buy it, get the fatory manual.
