Angry I pulled my Perma-tune out and it failed the bench test...

Pins 1 to 4 should be 3,300 ohms, but mine shows open. The car does start and car run fine, but I've been having problems with it stalling when it warms up.

Pins 1 to 4 being open indicate the high voltage is out (according to Permatune). If that is true, I kind of wonder how the car ran at all?

Go with Bosche unite if you want stock or if you don't mind doing little wiring go with MSD.

Why don't you talk to Permatune and give them a chance to comment/fix it? When installed correctly, they are great replacements for the $$$ stock unit. Mine worked flawlessly for years.

I did call and talk to a tech there. He said there is no repair available on the older units and suggested the new more robust black unit they sell.

I have a MSD 6A I think I will install this weekend .... I hear they will work ok. I just have to hope the tach signal is correct for my 82 VDO..... that and come up with a coil.

Use the MSD blaster ignition coil, Pelican should sell it. The exact match up component.

Yeah, maybe I should have. I hooked up an Accel high performance coil and my idle is all out of wack .... way too fast. At first I thought I had a vacuum leak but checked everything and all the hoses are connected. The throttle plate is not sticking. I don't know if it's the coil, but I will change it and find out.

The only bummer is, the tach terminal pushed into the MSD housing, so now I have to try and disassemble the unit to repair the connector.
