you are hooking the green wire to the connector next to the bat power lead on the cap? You may be missing the ground strap in the middle of the 3 wires that come from the dist to the cap. It's sold separate at parts stores as RR204 (NAPA) and hooks to the side of the coil. Without it, the coil overheats and it can blow out, taking the module with it. The previous owner of my '82 C20 with 454 got mad after the 3rd module, second dist and second coil and sold me the truck for only $1200. (it also had a bent pushrod and pulled rocker stud) $40 in parts later, and it has latex me 5 years (now going for sale since I will have a Jtruck to haul 5th wheel soon. ) From: "Eddie Stakes" To: , Cc: woft2@xxxxxxxxxxx Subject: [AMC-list] Fw: question about tachometer problem Message-ID: Content-Type: text/plain; charset="utf-8" Tom below is having trouble hoooking up his tachometer now that he has changed off a points sytem, anyone wishing to help please feel free to give him a shout and copy your reply to him and thanks in advance to all who might reply. Eddie Stakes 713.464.8825 eddiestakes@xxxxxxxxxxxxxxxxxxxx www.planethoustonamx.com ----- Original Message ----- From: woft2@xxxxxxxxxxx Hi Eddie, I have a 1974 gremlin 232 ci engine I just changed the points dist. to a new gm coil on cap dist. The problem I have is the tach worked fine with point dist. Now with the new dist when I hook up the tach wire the engine dies. Double check the wiring looks ok. Is there some kind box I need to make this work? Thank You Tom Tente. -------------- next part -------------- An HTML attachment was scrubbed... -------------- next part -------------- An HTML attachment was scrubbed...
