I have been studying and looking at the relay. It shows on the side of relay that when power is across 30 and 86 they both turn on? The 86 wire goes to a switch in cab and other side of switch is grounded. So when I turn on switch it actually completes the circuit buy grounding. Is that correct? And is it OK to have the #30 wire connected to the battery terminal on the voltage regulator? Thanks, Grady.
