I just recently put my MK1 Caddy 1.6 turbo diesel project on the road. Every now and then, mostly when driving at night, everything will go dead. Instrument cluster lights, headlights, even kills the power to the IP solenoid. Then, before I make it to a complete stop on the shoulder, if the key is still on, it will pick up and run again with all the lights back on.
It seems to only happen when the cooling fan comes on, but is it supposed to turn on at freeway speeds?
I have not found any fusible links in the Bentley manual, and all grounds seem to be in good working order. Should I remove all grounds anyway and clean them again?
Off subject, there is a sensor that goes on the radiator support with 2 wires going to it. Is this a wind speed sensor that is supposed to kill fan power at freeway speeds? I recently found it in my box of "extra" parts and realized I forgot to install it.
Thanks for any help.....other than this little glitch, the little truck runs fantastic!
