Using a 24v relay on a 12v vehicle ??

Post by bj42turbo »

I accidentally picked up a 24volt relay instead of a 12volt relay, can I still use it for driving lights on a 12volt car

Not really, no. There's a faint possibility it will trip with only 12V across the coil but you wouldn't be able to rely on it even if it did.
This is not legal advice.

Yep, tends to be marginal operation. I once ended up with a 24V (air valve) solenoid on a 12V system. Depressurised, it worked OK - could hear it switching. But once the system was pressurised, it wouldn't switch. That had me scratching my head for a while...
