GPC with constant WTS lite
My 92 F250 7.3L IdI has a serious problem with the WTS lite. Initially turning the key on gives no WTS lite even though the GPC energizes and the GPs heat up. after 10-12 seconds, the controller cycles normal in the after glow mode and the WTS lite cycles from dim to less dim. After that, the WTS lite comes on solid and stays on. The truck starts normal,and the WTS continues to stay lit but its at less than full brightness. Replaced the controller and GPs (Autolite 1108s), changed the alternator and external regulator, checked most ground leads. In dash voltmeter reads low, barely coming off zero only during the after glow cycling otherwise reads zero, I think all the in-dash gauges read low. The only thing that I believe to be incorrect is that the alternator S lead reads only 6vdc, and that after starting the truck battery voltage very gradually goes from 12.3 to 13.5vdc, but it takes several seconds.
