Voltmeter redneck engineering

Thought this may interest/appal. (delete as applicable). Some redneck engineering following my ignition system upgrade.

I wanted a voltmeter without sprouting another gauge pod or modifying the dash.

£1.75 including postage on ebay - electronic voltmeter readout. 2 wires - +ve/-ve and voila - anything between 3-30v it reads. Perfect.

I took a piece of platic from a computer server rack blanking plate, made a mounting hole to hold the meter and mounted this on the angled frame of the ashtray surround. The objective is to keep the display angled toward the driver, but only visible when the ashtray is open.

Long story short, works a treat. Invisible when I want it to be, visible without moving my head just by opening the ashtray. Could be removed if needed with no obvious damage.

Not everyones cup-o-tea, but perfect for my needs. Thought it may be of interest to anyone with a similar requirement. Just got to finish the wiring through the bulkhead and I am good to go. :)

Ta-da.

Got lucky. Just before tapping through the bulkhead etc I realised that some previous owner had fitted a modern-ish stereo at some point wheich I disconnected when I got the car. Sure enough, the spurs were there off the fuseboard, so I just used those. Perfect. 12.5 when circuit closed and about 14.5 when car running. Job done. :)

That's far to good for a redneck !!!!
Great job. And a good idea. :thumbright:

The real redneck version involves sticking the wires on your tongue and guessing the voltage by severity of spasm ! ;)

Same as what I've done but off the old Mopar radio wiring. Only measured about a .25v drop (At Battery Posts vs At Gauge Location). Not bad for 42 year old cable! :thumbright:

I like that a lot.

Nice work.
