Looking for some insight on the turn signal on a 7140. The flasher seams to be working but no lamps are working. I've sent power through the haeness to each lamp individually and they work fine but not with the flasher. Anyone ever experience this before?
One last wierd part. When you apply the brakes and turn at the same time the side that turn indicator is on shuts off the brake light but its not flashing. This thing is driving me krazy. Thanks for any help

Hey Niel!
Have you looked at the emergency flasher?

Ya' i started there. Right now i've bypassed it all together by wiring the flasher directly off an ignition hot source. Right now a painless kit is starting to really look painless

so is the power going thru the oem flasher or not?!

Yes i have ingition hot to the flasher and power from the flasher to the turn switch. Its not grounding anywhere in that area and i don't think its grounding at the light themselves as they work when i aply 12v to them from under the dash. I bypassed the emergency flasher switch to see if that was causing it and it dosn't seem so???? I'm at a loss as to what to check next

Unplug the leads going into the TS switch [1 plug on the 71 IIRC and jump the wire from power lead to each of the TS outputs.

IIRC, wiring is as follows: solid green=power imput, green with yellow stripe is one side, green with orange stripe does the other side. There should be at least two of each color striped wire.

The exact same thing was going on when I got my 45 pickup.

Sorry, but I don't remember how I fixed it>:shaking:

That's to be expected. If the flasher isn't working, the brake light wouldn't affect it. When the trun signal is applied, it breaks the circuit from the brake switch, and applies the circuit from the flasher. down at the base of the steering column is the turn signal switches.

Chances are, there is too much corrosion/resistance to make the turnsignals flash. one fix is to clean up each connection point, specifically at that column switch. You could also try a "heavy duty" flasher, but you won't find one that plugs into the toy harness.

I don't think the painless harness has a turn signal switch, so even replacing the harness won't be of great help.

To get the flasher to work, there has to be enough current draw to heat the coil to break the connection.

Got Ground?

A lot of time oddball electrical gremlins will appear due to a poor ground.
The "ring terminal with a screw through it" really doesn't work for ever as a decent ground.

I'll remove the screw and clean up the hole and ring terminal. Smear a little antiseize on them, then reassemble to get a good ground.

Found some "piloted bonding brushes" surplus that are great little tools for this reason. Took a while to find the name of them! (pictured one below) Aircraft suppliers carry them, but darn one look at the price is enough to scare me off! Anyway chuck into a air drill, fire it up to get a nice clean spot, viola (that and using a screw and nut to keep the contact good). [Edit... brush is less then a 1/4" diameter across. Tiny. Pilot is about right for a screw hole]

Thanks Pal!

I'm not sure how as i ended up just rewiring them all together. Best part yet is the rear heater now works as do both speeds of the wipers. It's amazing what you find when you look long enough.
Thanks again for all the help

terry will be pleased:D

And you thought I was joking:)

that's some great tech!:flipoff2:

Nice!

We probablly had the same issue.
