sr2 Posted October 6, 2023 Author Share Posted October 6, 2023 My thought process was to have the light light up only when the fan was actually powered up, .i.e I'd be covered in the event of a relay, fuse or switching failure. 2 Quote Link to comment Share on other sites More sharing options...

I think flyingbrick's idea of essentially putting the bulb in parallel with the relay coil should work? Quote Link to comment Share on other sites More sharing options...
Flash Posted November 29, 2023 Share Posted November 29, 2023 You did a top job on the gauges Simon and the ignition switch is an absolute work of art. You just can't beat that vintage look. Quick question for you regarding the Nissan wiper motor that you used. Do you know what model Nissan it came out of? I played around with a few options for the Thames, but I'm not that happy with my current setup so I'm thinking of doing a rework and your setup looks ideal.

Lord Gruntfuttock Posted November 29, 2023 Share Posted November 29, 2023 A shunt resistor will let you run the 20A ammeter, just be aware of parasitic load if it's connected all the time? Will depend on value of shunt resistor, only 12V pushing it so anything over 1kohms total resistance (including parallel meter resistance) means you're looking at milliamps... https://www.rohm.com/electronics-basics/resistors/shunt-resistors Quote Link to comment Share on other sites More sharing options...

Hi mate, the wiper motor was off a Nissan Tilda C11 (2004 to 2011 I think?). 1 Quote Link to comment Share on other sites More sharing options...

(i.e. I'd need to use a volt meter). Quote Link to comment Share on other sites More sharing options...

Just did a quick double check on Google - it's actually a front wiper motor. 1 Quote Link to comment Share on other sites More sharing options...

Thousand Dollar Supercar Posted December 22, 2023 Share Posted December 22, 2023 I think you need to fit a hazard light function so the trafficators flap like wings. 2 1 Quote Link to comment Share on other sites More sharing options...
tortron Posted January 7 Share Posted January 7 You can get all those trafficators going again. It's usually the shellac on the windings is failed and shorting. Fairly straightforward to rewind by hand, not too many wild turkeys cos there's 700 odd coils 1 1 Quote Link to comment Share on other sites More sharing options...

I might have some further in for long deep in my morrie build as it was about 2007 I did it. The resistance is probably in the manual somewhere, il see if I can find it Quote Link to comment Share on other sites More sharing options...
