flasher relay or bulb socket? Hazard button?


Recommended Posts

Hi folks, I'm having indicator trouble. I suspected the flasher relay so I shorted the connections on the fuse board with a little connecting wire, but it didn't make any difference. The bulbs have all been changed. The rear side lights come on and stay on when I turn the light switch on. turning the indicator lever has no effect. The front side lights don't come on with the light switch or the indicator lever. the front indicator bulbs (the large 382 amber bulbs - this is a '72) come on with the headlights, but they don't flash. Both the dash indicator lights come on when I turn the light switch on, and they don't flash when I turn the indicator stalk. Also, the hazard switch doesn't click out when I pull it. Headlights work as they should. Brake lights work perfect when the dash light switch is off, but when the headlights are on, the rear (red) lights come on and the brake lights are barely brighter than the rear lights.

If I remember correctly, the indicators worked on one side only when I got the car, and the other side would come on but not flash. The hazard switch was always stiff, but used to work ok. The relay used to click up until a few weeks ago. it doesn't now. The rear side light accessed in the trunk is corroded and needs replacing. I got it working to test it, with a piece of tin foil to make the connection. I haven't done anything with the electrics recently, but I painted the engine and some frame parts, and had the battery out for a while. car is driving great.

Does is sound like I just need a new flash relay and two front (pigtail?) side light harnesses? What can I do with the hazard switch?

Did you check the flasher above the steering column?

I did not Dennis. what do I have to remove to get at it? Is that not the indicator flasher I had out?

You should be able to reach it without removing anything. It’s on the top of the bracket that the steering column mounts too. I know my 70 & 71 have it but not positive on the 72.

Another item you may want to check is the turn signal switch in the column itself.... If the hazard switch isn't clicking, it may be worn out.1386661771_Turnsignalswitch.jpg.fb7c35dc3846faed80840657e4b84413.jpg

I swapped relays to see what happened. The turn signal clicks normally, but barely flickers the lights. The dash is a different story. Both turn lights come on and the gen and oil lights flash. 
bad ground?

Paul, check all the bulbs on the outside. Make sure they are all functioning properly. Sounds like some are not. You didn't have this issue until you changed all the bulbs. Sounds like a backfeed.

All I remember is:

the 1156 bulb has ONE element and ONE spot to connect power to, via the socket. It is used in the Back Up lights.

the 1157 bulb has TWO elements and TWO spots to connect power to via the socket and I believe were the only ones used in the Ft (one bulb each side) and Rear (Two bulbs each side) T/S and illumination. 

The small little lights are used in the side markers.

I bought some replacement 1157 bulbs over 10 years ago, and they had a slightly smaller base and it was loose in the socket causing some intermittent problems. I bought some higher quality bulbs and they fit much better / tighter.

GROUNDS are very important and need to be checked.

Side story, It's 1969 and My friend was replacing a bulb on the taillight of his 64 Chevy but couldn't get it to work.

I took a look and found he had jammed a 1156 into a 1157 socket!!!!!!!! Dah..

Good times...

ALSO!!! What is not stock or was changed?

The largest cause of taillight and T/S problems I remember repairing, is after someone ADDS A TRAILER HITCH WITH WIRING!!! or a an "A Pillar" adjustable spot light.

sadly the turn signal flasher(if i remember correctly-no guarantee on that) is in a much tougher location up under the dash...i think the electronic flasher is more reliable than the old bimetal style... go with   EF552?   again please correct me on this also...been a while

Sorted. 1157 bulbs are called 380 here - dual filament 21/5w. I think it was backfeed Tom because I had single filament in there 😬. Wasn’t paying attention. Loads of corrosion though, need to replace a side marker and a bottom rear bulb fitting. Hazard switch broken but turn signals are good again. Cheers

If you're talking about the lenses on either side of the grill, they came from the factory as amber...... Being a signal light, the colour differs from the headlamps to provide contrast when indicating a turn.

Here is my 71, No A/C Monte fuse block. The FLASHER shown is for the 4 way flashers isn't it?

I believe the T/S Flasher is attached to the steering column. I can't find a picture to show that one, sorry.

Please correct me if I'm wrong.

I remember when I added a trailer for my snowmobile, the T/S would flash way faster!!!
