Richard... I'm an electronics moron. Therefore, I'd welcome a picture. If I go to my local American Electronics store, and ask for a 750 ohm shunt resistor, will they understand? Is a shunt resistor different than a resistor? Wired right across the + and - terminals?
Hi Ken. No its just a regular resistor, the term shunt just refers to the manner in which it is wired in parallel with the sender.
I bought mine from Maplins a chain electronics outlet in the UK. It's a metal film 0.6 watt with 750 ohms being a common value, costing just a few pence. Will post a picture when I can but just used crimp connectors with suitable eye tags. One under the central connection the other on the adjacent screw where the loom ground attaches.
Just left the electronics store. The .6 watt seems to be made of unobtainium but he said that wasn't crucial. I have a 750 ohm 2% HW175 and will be installing it shortly. Then a fill up and observation! I'll report back.
