FSD/Fuel Driver/Run Solonoid

[T.C.Mac]

Beastmaster,GMparts guy,Vern B,
Thanks again guys, I installed the FSD with a new PMD and that solved the problem. Food for thought, my Auto X-Ray scanner did not pick up the defective driver. The scan showed everything normal. It doesn't list HUMMER in it's software list so it may not be Deisel compatable. A simple 12 volt test light showed no power to the positive side of the "Run Solonoid" in the key on position.
The FSD Cooler is a simple installation but the instructions with the unit are vague (Especially for the H1) so you will have to get creative. It still appears to be a good "preventive maintenence" item for those concerned about reliability.
Many Thanks for the input
T.Mac
