[TR] electrical issue

[DAVID MASSEY]

As you may have seen in a previous post, many (most?) TR3's and TR3A's had a fuse added to this circuit to protect against accident damage to the tail lights causing a short circuit.  This in-line fuse may be in the passenger footwell or under hood near the voltage regulator.

 The brake lights work as do the turn signals.  All gauges work as does the heater fan.  Only the tail lights and dash lights do not work.  I believe there are only 2 fuses for the car, correct?  I've replaced them both.  I can find no loose wires under the dash.  The wiring harness was replaced 2 years ago with a high quality harness.  Everything worked until the paint job.
Thanks again all for your info,
Allan

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,
