i purchased a replacement dist. for my 340 (accel 59301)...the first one was a used unit and I could not get the car to run at all with it...this is my second unit now and it is new...plug wires are new and have the proper orientation..brought # 1 up to tdc and set the base timing for it to fire.. no go...strangely enough....like the first unit..I put the "old" dist back in and she fires right up..???I did previously have an alt issue and had a wire improperly hooked up and may have back fed my chrome box..the car always ran but had a miss due to the needle bouncing .although it didnt seem to be an issue with the old dist..is it possible I may have damaged my box???I thought the accel units were plug and play...i have plugged...but no play??? what am I missing???? Oh..I did pull the coil wire off when cranking the motor...no spark...? But when I turned off my ground(battery cut off@neg term) I saw a spark at the coil wire...what am I missing here?I dont believe i could have gotten two bad units???accel has always been some pretty good stuff?? I really need some help????:angry7:
