My original Jensen Rev counter seems to be dead. The sender unit was missing so I tried hooking it up through a 12v to 12v transformer, and nothing. Then tried a direct hookup and nothing. I guess the sender using is something more complex. This is a single spade connector type. I haven't pulled it apart yet.

I've borrowed another earlier rev counter from Charlie at the Oxford Classic Volvo place and that would just spin around to full revs when power was supplied. Its a strange two spade connector one I couldn't find decent wiring diagrams for. I pulled it apart (with Charlies blessing) and its just a transformer hooked up to the electro magnet windings. No resistors or diodes in sight!

I'm now looking for a simple induction pickup type (The one where you wrap the low tension coil wire around the pickup) to see if I have any luck with that. Anyone have one around?

Thanks
