Brake light frustartion

Dart Vader · Post by **Dart Vader** » Mon May 01, 17 5:12 pm

Last weekend we finished my car.

All seemed good all lights worked and all other indicators etc

Today is an odd one.

If I push the brake pedal the brake lights come on but so does the front indicator turn light and the one in the grill. I've converted the front side driving lights into indicators and tell ones in the grill used to be driving lights but now are indicators.

When I disconnect all the loom going to the back lights and hit the pedal I still get the front indicators come on and stay on. They don't repeat.

Earth's seem ok at the back.

Any ideas?

Justin, I had a similar issue when converting my lights. I'd go back with a multimeter and check every earth more carefully. One of my rears needed a separate earth wire soldiered from the bulb holder to the body. It fixed the problem.
It all looked good until tested with a meter.

As Miles said Justin.
My old truck used to love a bad earth on the lighting circuits.
It doesn't take much to send it all wonky !!!!

OK cheers guys will try that.

The car is ready apart from that and wanted to take it out today to scrub off the front discs and just check the final few things.

Thx

Maybe your indicator switch,mine plays up sometime and effects the brake lights,but im on origianl reds,give the stalk a wiggle and see if anything happens.

Not to teach you to suck eggs, but did you run a new wire from the brake pedal switch to the brake lights? Best way to convert is to use the factory indicator wiring to your "new" indicators, and run a new brake circuit, completely isolated from the indicators.

Adam, I did the same. Reckon Justin's is an earth jobby somewhere as I had similar symptoms.

Sorted a better earth to the rear lights and retraced the wiring at the brake switch. All was good.

Then went to take it for a test run. Now stuck in first gear.....grrrrr

Is it column shaft Justin? Got headers?
Been through that. Check everything especially the pins that hold the linkage together in case one has broken off. The gate assembly that connects to the column shift down rod can catch against headers.
Even with my TTIs I had to massage parts to get clearance, in fact I had to buy a new gate piece to clear the headers as the headers run through where the original piece fits from inside chassis rail to the side of the trans mission.
