[QUOTE=Shorebilly;1363289]but we discovered that over time, wear, use.....some German components tend to weaken in the magnetic solenoid area....allowing the timer (or whatever) to drop out....causing the contacts that it controls to open or close......

I have not looked for a schematic of the Glow System this AM...but from reading here, I understand that the indicator light is on a timer that is unrelated to the Glow Sequence......perhaps the timer is getting weak and dropping out, just lighting the warning light.....pay attention when you hit sharp bumps/potholes and such.....if they seem to go together, don't worry about it, too awful much !!!!

Hmm, good point, I hadn't paid any attention to the road rumble when it starts to happen, does seem like it never does want to do it standing in my shop though....
I have 2 spare modules, both from newer models that are slightly different design (2 mount bolts and some odd extra wire with a pin connector on it), and they screw together from the top it appears, hopefully they will work or parts thereof will...My plan is this weekend to attack my existing module with a dremel cutoff wheel (old 3 bolt module that is glued together) and get inside it for inspection. I am coming to the conclusion I am getting a module that thinks its seeing something thats not really happening, maybe I'll get lucky and find a bad solder joint or something in there. The car did start well this morning, but the light is still flashing after all of yesterdays cleanups and tests. I think I'm also going to pull the gp's for inspection too just to eliminate any doubts of the tip condition, want to do a compression test too but I need to fix this cam with the bad lobe first, anyone got a good one for a non turbo 617.912?
