Currently, I have a 3-1/8" electronic tach w/ hour meter powered by a transducer attaching to the tach drive on the engine. I have a header tank and no electrical system. Most of the new electronic tachs w/ hour meter I've found require 12V power. I can't find one like the one I've got and would rather not try to route a mechanical tach cable around the tank. Guess I could use a 90 deg. drive if I had to. Does anyone have any suggestions?

Werner" Subject: Re: RV3-List: RV-3 Tach Installation Why not use a small 12V source just for the replacement tach. I would certainly not mess with a mechanical tach cable. Do you use any Radio and/or Transponder in this airplane? If so, how are they powered? I think having a small battery would do the trick for a few hours of flight time and then you can recharge it over night. do not archive ----- Original Message ----- From: Sandifer, Eric (MED US) To: rv3-list@matronics.com Sent: Wednesday, May 23, 2007 12:30 PM Subject: RV3-List: RV-3 Tach Installation I need to replace my tach and am having trouble finding something suitable.

Lithium 20 years battery, hooks to the back of the mag switch and is very accurate. When it's not recieving a pulse from the mag it registers tach hours. Highly recommended.

The cable rpm come straight to instrument.
