VDO tach and MSD

Former Member

I have a VDO tach that has the directional signals built into it and another light at the bottom. The engine is a type 1 VW motor. The tach worked fine until I did the following.

I installed a MSD 6A Capacitive Discharge Ignition System, a MSD 8485 Distributor, a MSD 8203 Blaster Coil and a MSD 8920 Tach Adaptor. The tach was then intermittent. It worked sometimes and then not. I thought the MSD Tach Adaptor was defective and sent it back.

I just installed a new MSD 8920 Tach Adaptor and now the tach does not work at all. I contacted MSD and made the checks on the tach adaptor. It appears to be working OK. But, the tach is inoperative.

Do you have any suggestions on what I might do to get the tach working again?
