I've got a 52mm rev counter that's been always been broken. I was thinking of swapping it for a voltmeter wired direct to starter battery. Anyone know whether one would drain the battery quickly?

Hello,

Well, as you have a leisure battery, why not wire both batteries via a 3 position switch to your volt meter...

That way you can see the batteries condition and avoid 'phantom' drain

Pretty much anything that has diodes will drain.... hence master cutoff keyed switch..

The changeover switch can be anywhere convenient.

Cordialement,

Good Idea. There's already an unconnected switch so I'll just swap it out

Depends if you want a rev counter or a volt meter?

Why not fit a clock, or a temperature gauge?

The options are endless.

I have 2 voltmeters fitted exactly like in the video, 1 for starter battery and 1 for leisure battery. I have a switch so can turn display on and off as chosen.
I also have a rev counter, which didn't work for years, I just replaced it and it worked fine though I re-wired the power feed up to my auxiliary busbar fuse box.

As its an auto, don't really see the point in having a rev counter. Clock is standard fit. I think I'd find a voltmeter slotting into the existing cut-out the most useful but thanks for the ideas

Albeit not in that location i did exactly this - a voltmeter controller by an on-off-on switch so I can monitor both batteries but also turn the meter off to stop that (admittedly very small) residual current draw.

I do find it rather useful and watching for a voltage jump even tells me when the split charge relay has kicked in (obviously do not distract yourself whilst driving etc etc!)
