Thanks all, yes I have power to the panel, it is the two row of fuses that are energized by the ignition. I see the three big relays and have interchanged them and got nothing, there are two rows of relays at the bottom of the panel but none are labeled and there is no diagram. I believe that is where my problem lies ,but how do I check the relays??
There should be power on one side of the relay contacts and once the coil closes them, there should be power on the other side of the contacts. Ignition switch on should produce power to one side of the relay coil and if it does not, run a 12vdc jumper to the coil's hot side and see what happens for beginners. Also check for an established ground on the other side of the coil and keeping in mind that some systems will actually switch the ground return, like a brake switch or horn button does. Some of these relays may have a socket that's soldered on the PC bd, which makes it tough and in which case you can start by unplugging the relay and checking for these voltages there.
