Wiring to ignition light

Recommended Posts

Hi Roger,

it should be a filament bulb so is not polarity sensitive. The wires on the bulb can fit either way.

 

Do be careful if any other wiring goes to these bulb terminals.

Thanks Roger,

I suspected that was the case, but I didn't get any wiring fitted on the the car at all,

and don't won't to chase the inevitable phantoms all my wiring jobs seem to end up with!:ph34r:

I've also 2 more Autosparks looms to fit to 2 similarly afflicted, but non TR,

projects, and it will be nice not to have to dither about on the same matter!

Many thanks

 By convention a 'live' feed would be connected to the centre 'pip' on the bulb, so that the metal shroud of the bulb is not live.

However, on that particular bulb both sides can be at supply potential so it doesn't really matter.

Hi Rob,

Yes, understanding RogH and that the bulb is polarity insensitive,I'm working on the assumption that the bulb contact will become the 'negative' in my case direct from the ignition switch,and thus the connection to the control box wire will be 'positive' for the purposes of my not ever so electrical brain.

Getting there slowly, but the wrong age to start from scratch!!

Thanks
