Wiring & testing GPW help!

Help please

 

In attempt to rewire my jeep -a previous owner did everything in red wires and missed out some links etc. I have 2 queries...

 

1, Fuel guage -works but reads low and when catching float and moving up to top of tank it still reads only half full - is there a method to calibrate the sender to guage? or test same

 

2, Ammeter - the wires were a total cluster and trying to rewire previously wrongly wired cables (which were burnt out) the ammeter only moves slightly off centre mark -it worked alone and same with test meter -2 amps reading average- would it be possibly the regulator (previously wired up wrong way) which needs polarising or can it be generator -these all worked before the wire cluster and burn out.

 

The jeep has been converted to 12v and appears to work fine otherwise, starts and runs fine

 

thanks

Gary it's a generator that is polarised not the regulator box, has the generator been off or stripped? That will effect polarisation. If the fuel gauge and sender were originally 6 volt and is now working on 12 volt, yes that will affect the reading you need to add a resistor. Regulator boxes are very touchy have you opened it and looked for any obvious damage?

Nothing has been changed only rewired etc but nothing opened up -it was 12v previously and all that has been renewed was new switches etc and lights but nothing on the charging or fuel side.

I also 'flashed' the regulator as per it's instructions (written on it) to polarise

 

thanks

Never seen the instructions on the regulator. Was it connected to generator at the time? Elecktrickery is dificult to diagnose from a distance. First thing go through the wiring diagram and try and find any place the two circuits cross. Go from there.
