Another turn signal question..dash indicators

[Monk67]

Car I am having delivered today I found out,last minute, the turn signal lights
in dash don't work.
All exterior signals work.........what's one of the first things I should look for?

Plan on pulling dash next week to check continuity and maybe ground.

Thanks in advance

If it has fender or hood mount signals you can see from the driver's seat, it may not have had signals in the dash. Some were built that way, but people wanted signals in the dash, so many were converted. My granddad was one.

What car?
what year?
What trim level?

Could be as simple as burned out bulbs.

Remember to disconnect the battery and amp guage wires

Ooops..........sorry

My bet is the bulbs are burnt out.

My 67 dart gt has fender mounted indicators and dash indicators.

You SHOULD be able to reach them without pulling the cluster. Note there are bulb adapters that are smaller than others and make bad connections.

I'm hoping it's that simple........car has gone through a total resto and would seem odd that both bulbs are out but will be my first thing to check.

If it had factory fender or hood mounted turn signals sometimes they left the bulbs out of the dash.

 

[Monk67]

Ok.........checked car out..........first emergency flasher doesn't work and I notice on wiring scheme indicators go through this switch and when they do flash on
out side they're very quick.
So I'm thinking changing flashing switch out if I can find one.

No they don't go "through that switch."

Here is how a 4 way flasher switch works in pre--"on the column" switches

First of course you have two flashers, one for 4 way (powered at all times) and one for turn (powered through key switch

When the turn signal switch is centered, the brake lamps are connected together by that switch, and connected to the brake light wire going to the brake light switch. this of course is so that when you tromp on the pedal, power goes through the TS switch and is routed to both brake lamps

That is ONE external wire...........the brake light power wire to the TS switch

The left front and right front signal lamps are separately fed to the TS switch AND THEY BRANCH OFF and feed off to the dash indicators and the fender indicators "if equipped."

So that is two more wires

HAZARD SWITCH. The hazard switch up before the switch was incorporated into the column is a 4 terminal switch, and when off, all of the terminals are connected. One goes to hazard flasher output, one to left front signal lamp, one to right front lamp, and the remaining ties in to the brake switch wire previously mentiond

When you engage the hazard switch, ALL FOUR terminals are connected together. This feeds the flasher output to the brake switch wire and on to the two rear signal lamps, and to the left front and the right front signal lamps, causing all four to flash

AGAIN, the dash (and fender) indicators ARE SIMPLY branched off of the left front and right front wires so they flash as well

Got it.........well flasher switch doesn't work so I'll have source one out.
Reading through your explanation.........what do you think issue is?......also seems when the outside signals are on, they flash really quick, almost too quick.
Thanks

Flashing "quick" or slow is usually an indication of wrong/ missing/ non working bulbs or too many bulbs--or just a bad flasher. All traditional flashers depended on the load on them to work correctly.

A common problem in the day was a "standard" low capacity flasher would flash fast when a trailer was added--more load would heat it up quicker and it cycled faster. the "standard" heavy duty flasher was 552

It's very common for the dash light bulb holders (sockets) to have a broken tab causing a loose connection with the circuit board. That's the first place I would look. Check the bulbs at the same time.

Even when they are new and not broken they can loosen! After bench test I put a silicon dab to either side to hold them there! Reason being good vibrations!! 7 years and doing Good!
