Would this be the right wiring for the regulator.
Positive / A live feed coming from ignition switch.
Negative / A wire run to earth / chassis. F / A feed run to the fuel gauge, then from the gauge to the petrol tank sender.

Are you looking to fit a voltage stabiliser so the feed to the instruments is a constant 10 volts? The item pictured is an alternator control box so I'm not sure it will do the same job.

Thank you Mr P, it is a voltage stabilizer that I require to feed the instruments, could help me by telling me what I require, I have had to rewire the Ambulance and I am more mechanical than electrical

I have replaced with original type and then the little electronic one. I have also used a 9v battery when I was waiting for a replacement to check the fuel going on holiday.
