First Gen Turn/Hazard Flashers SLOW at idle

It seems my turn signal flashers become super-slow at idle. When there is additional stuff on (like lights or heater) the flasher almost stops (real slow). Above idle and at cruise, everything works fine.

With the exception of a solid-state voltage regulator - my electrical system is original. I know first gens have low power issues at idle (see yellow headlights) - Do you think this may affect my original thermal flashers and cause them to not heat up and behave properly?

Has anyone else experienced this? Do you think an Electronic or Heavy Duty (as opposed to Thermal) relay may make the turn signals flash more consistently?

Thanks,
Dave

Re: First Gen Turn/Hazard Flashers SLOW at idle

Swap in a 552 flasher or equivalent after making sure all the bulbs are correct.

Not only is the design alittle low by today's standard, the wire dissipates power as heat when current is flowing. So if light bulb requires 1 amp to light, there is more power/current from the power source to compensate for the wire loss, plus all the connections.

Remember you have 2 flashers.

The one on the fuse block is for the flashers.
The one under the dash behind the radio is for the blinkers.

Re: First Gen Turn/Hazard Flashers SLOW at idle

And when you increase rpms...900 or 1100 all is ok?
Check bulbs etc are correct as Everett says...
But I would also suspect the alternator...worn bushes/ bearings and /or brushes will do that.
With the water pump/alternator belt up tight, that puts a huge side load on the water pump and alternater bearigs...which is the only thing that ever goes wrong with both them...normal running around mine sqweel at a little over 4000 rpms, quite bad...
my pumps and alternater bearings last decades.

Re: First Gen Turn/Hazard Flashers SLOW at idle

I had this problem for years. Just lived with it. I didnt know there was 2 relays. Mine had the original blue relay in it and when I removed it, it broke in my hand. Replaced the relay and it works great now.

Re: First Gen Turn/Hazard Flashers SLOW at idle

I did replace my indicator rely yrs ago with a modern one that always flashes at the same speed...this was because of extra load of the trailer lights when towing..

Check your voltage at idle Vs. at say 1100 rpm.... Alternator may be weak,going bad,belt slipping,or bad brushes ???? Get it tested/rebuilt.

Re: First Gen Turn/Hazard Flashers SLOW at idle

Thanks for all the great info everyone.

I put in a 552LL turn signal flasher relay (under the dash near the ignition switch) and it works perfectly at all rpms now. It is a Triton electromagnetic relay. $6 from the local parts superstore and made in the USA too! What a quick easy fix - would have done it long ago had I known.

Yep,,same problem I had. Always thought there was one relay. Glad you found the problem.

That would be me...I'm glad it is working good for you. That flasher was made in Hendersonville, Tennessee, by a crew of really hard working, caring folks. If you have any issues PM me and I'll make sure you are taken care of.

The 552LL is less voltage dependent than the 552 thermal. That is probably what is fixing your issue.

Best,
Robert
