Morning all.
I am currently getting my late mother's '75 845 TL back on the road. The engine and box are out so I have great access to the wiring loom. It has the 2nd type dash.
I want to keep it looking as original as possible inside and under the bonnet, but I have a few ideas to make it reveal its secrets to the driver before it's too late...
I would like to:
1) turn the red oil pressure / overheat lamp into an ignition warning lamp (moderate)
2) turn the redundant amber heated-screen lamp (the HRW switch has its own intergral telltale lamp) into the oil pressure lamp (easy enough)
3) turn the voltmeter into a temp gauge using a transmitter in the water pump where the overheat switch is located. (Hmmm...)
The manuals I have (including the genuine Renault factory one) are to say the least very vague about how the voltmeter works. I'm sure that with a lot of trial and error I could get there, but I was wondering if anyone had any tips? Some tinkering with sender resistance might be required but I could wire in a small rheostat for initial setting, and set up using Infra red thermometer.
Any tips would be greatly appreciated!
Cheers
Paul
