hi I have a hj60 2h 24volt from 89. it does not want to start. I have taken the whole car apart and now I have assembled everything and have installed the electrical system. I have measured and have 24 volts for the starter motor that works. I have electricity for the generator. I have checked the two relays at the air filter and they click. I have electricity for everything in the engine compartment but do not get an instrument lamp or meter to show anything. how do I test the relay on the screen (see picture)
