Ahh I see what you mean so an ammeter is the better option than a voltmeter, you have helped a lot with that recommendation unfortunately I have bought a voltmeter but it was less than a tenner , I will check Amazon for the ammeter this forum is valuable for this reason someone with the knowledge comes up with a better option I know what you are saying about it being something to worry about but I really would like a visible display of the battery's performance cheers max.ps I see you are this side of the pond :) all the best buddy
Get a good ammeter as this will be one more point of failure in your charging system since it will be wired in series not parallel

Cant you run a wire straight from the battery?
would that be the best way to know what the battery is getting in and out ?
Yes I could run wires from the battery but I would like it to turn on and off with the ignition so I don’t forget and flatten the battery

I use ignition relay on most of my bikes. Connecting directly from battery and using ignition switch to power relay. To much current thru the key switch usually end up with lower voltage. I use relay to power everything from heated hand grips to getting good voltage to my coils. To a more accurate voltage gauge. It takes load off of key switch and wiring loom. Do not buy cheap china relays. I’ve had the relays fail in less than a week. Try Eastern Beaver for relays. Sorry little long winded. Use accurate multimeter and check direct battery voltage to your new voltage gauge.
That sounds a bit too technical for me, unless you can give me a link to the relay and a short guide how to wire it in? I understand if it’s hard to explain cheers buddy

I’m not to artistic. But I will give it a try. Easternbeaver.com is where I buy relays.
