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.
