Correct me if I'm wrong - TRs never put fuses on light circuits

Good point.  it wouldn't.  But the information offered was a bit sparce.  Is it just the tail lights and do the brake turn signal lights work?

I believe there is a fuse for those lights somewhere in the harness.  It was a dealer upgrade at some point.  Later TR's have a fuse in the fuse block for that.

But how would bad grounds affect the dash lights?

I'd check grounds too - if the lights are grounded to the body and the body was painted they may no longer be grounded. Regards, Tony On 4/20/2026 5:38 PM, auprichard uprichard.net wrote: ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍

Yes – same circuit.  But I’d also expect the front side lights / running lights not to be working and possibly the headlights too.

Get under the dash and check the wires in and out of the light switch.

I have a '62 TR 3B. I recently had it painted. The painter took it apart to paint (fenders, doors, trunk, etc.). After bringing it home, I discovered that the tail lights and dash lights were not working. All other electrical items are working.

Everything was working before the paint job.

Thanks in advance for any help,
