Re: Help me understand the wiring - voltage regulator.
It's been a while since I have been in the sight. No answers yet. Well I'll give it a whirl.
1st off, Well, on the connect the starter switch to the battery's pos. When I expanded the thumbnail. I couldn't type here. I've been writing on piece of paper going thru what wire does what. Getting tired. Check the fuse on the orange wire going to the B terminal @ the reg. That gives power to the ign switch. #1 to B on the diagram. No power there? Key to start, nope. Key on, no power to #8? Bad switch if power is good to B @ ign switch.
On the starter and gen. Power to it makes it turn to start the engine. Take away power, the faster it spins it generates voltage and amps. Controlled by the reg. The field wire kicks in. Demand vrs output. Excitation. Reg's also need a sensor wire. Whats that? Voltage reg,s do 3 things. Regulate voltage values, amp values for draw on the system and A reverse current relay. To regulate call from. Is it needed from the battery or gen to supply. Regulate voltage draw from batt or gen to keep the system running.
