I have just converted my 1958 Ariel Square Four from 6V positive earth to 12V negative earth and installed a converted alternator with solid state voltage regulator (from Iron Horse Spares) in place of the DC dynamo and mechanical regulator. I switched wires on the ammeter poles but now my current reading swings wildly from one end of the range to the other. I think I need to place a resistor in parallel with the ammeter but don't know the amount of resistance I need. Any ideas, please?

It's behaving exactly like any other Lucas ammeter.


Take it out and fit an ash tray.

an typical 8-0-8 ameter will read in that range irrespective of voltage .

if the meter bounces is all over ... it may be vibration added onto the reading ( all too typical )
or
the meter is hooked up wrong ( also easy enough to do )
the meter does not have polarity
the meter is meant to show amp flow into or out of the battery .

Pete R - R.I.P. once suggested Click here

He was a very smart man, and this makes perfect sense to me.
