electrical sounds coming from my turn signal switch

[g-man]

When I have my headlights on my turn signal switch makes an electrical "bing" sound when the turn signal comes on. Interestingly the windshield wipers do the same thing. I haven't torn into my clam shell on the column yet but I suspect I will have to find replacement switch or switches. Weird how it gets alot worse when the headlights are on. They are on a different circuit.

Other symptom is that my intermitent wiper switch is acting up. Not wanting to turn off sometimes, going fast 2 or 3 times on the slow speed, not sure if this is related.

The problem could likely be bad grounds behind the dash. If the ground connection is poor, the voltage drops and the relays can't trigger with gusto because the electromagnet barely is strong enough to flip the switch. This can cause arcing inside the relay contacts (or buzzing) and cause it to fail prematurely.

Might very well be bad grounds. I've been through them once but might have missed something. When I put my head down under the steering wheel I hear it in the clam shell and not near the relays.

I will be taking the clam shell apart soon. I thought I saw on here a guy who bought a 62 series wiper/turn signal switch and it fit in a 60.

Update: after installing the new turn signal and headlight switch assembly I still had the pinging noises. After searching around on some old posts I saw where someone had fixed there's by cleaning the grounds in the engine. I tightened my battery terminal connections, cleaned the ground at the battery, cleaned the alternator hot terminal ring. Cleaned the head ground wire that goes to the firewall. And lastly cleaned the ground on the starter to the frame. No more noises.

Sounds like this is what you were chasing about the hazard switch too. Good deal.

No. The hazard switch is a separate issue. The toggle on the hazard switch is tighter than the old one. That allows it to get hung in between off and on. When this happens the contacts on the black plastic sliding arm is contacting (both simultaneously) the power wire for the hazards AND a power wire that feeds current to the turn signals from the ignition. This back feeds current to the ignition. I just need to loosen the hazard toggle a bit somehow.

I have a very evident click click noise from my wipers. I’ll have to check all my contacts too. Wouldn’t it be fun to get the volts up to 18 like @mwebfj60’s 60?

18 volts sound like too much. I have 14v coming from my recently rebuilt alternator. I would think 18 would mean a problem with the voltage regulator not doing its job.

Go check his latest video on the Phoenix build. He added a quick dash view of the 60.
