Hello all,
Ive done some searching on the boards to find an answer but it inst exactly the info i was looking for, so ill see if it can be answered. I have an 86GN with the LT1 alternator on it, and with all the stuff running ( a/c, fan on high, lights i get 13.5 at the battery, but i only show 12V at the fuse box. My gauge is getting that from the acc on the fuse box directly, so its accurate. how does the fuse box get its power, from the voltage regulator on the alt or the battery its-self? and also i found wierdness with the brown wire coming off the alternator, it has the 4 wire connector instead of the standard one brown wire. The brown wires are spliced together off the alt (there's 2) then down to one wire, then into 2 ceramic block looking resistors at 10 ohms, then spliced into the brown wire on the 4pin power master that is not being used (its vacuum brakes) I have the giant service manual but i cant read it well enough to see if the brown wire is just direct form the alt to the C100 on the firewall or it goes to other places. I know it isnt right, but i cant figure out how to make it factory or at least get me 13.5 like it should. Any help will be appreciated!
