914World.com _ 914World Garage _ power for add on gauges

Posted by: Mike D. Aug 10 2013, 12:49 PM

since I've added the type 4 engine to my vw fastback I want to add some 914 gauges. Can I use always on power for the gauge power? I'm adding a tachometer, oil pressure gauge, oil temperature gauge.

If you use a constant power source you will most likely just drain your battery. Should be able to use a test light and see what fuses have key on power and branch off of one of those, and/or try for a relay method so the draw on the fuse is only to drive the relay and not the gauges.

Do you mean ALWAYS on? Or always on when the ignition is on? The answer to the first is no, the answer to the second is yes.

I pretty much knew the answer. But I had perfectly good clock power sitting there and no more room in the fuse box. I made room and have switched on power.
Thanks
