Too much time on my hands, I'd bought one of these on FleaBay recently-


So I got a plastic box from Maplins and got to work with the dremel-


Bit of double sided sticky-


And with the car running-


Only draws 8.2mA so ought to be able to leave it connected, but will probably fit a switch when I fix it in permanently.
Nice afternoons work, there you go!

 

Your right WAY TOO much time on your hands....i want one !!!!
But you really need it inside the cabin...

 

Brilliant and I appreciate the neatness of your work rich, but as I'm not machanically minded, what does it do!

 

It basically does the job of a volt meter and tells you the voltage across the battery.

My Apexi RSM does this

 

Nice work, but you could have bought a voltage gauge for £10

 

I have boost gauge that does this, displays voltage for the first 60seconds.

 

£7 and an afternoons enjoyment.

 

Why is this a good idea? (sorry I've a lot to learn!)

 

I don't have boost.

 

Give an indication of the condition of your battery (not under load, before some smart A points it out).Girls HUH!
