87 442 , lights fluctuating issue

[HDwildcat]

So I bought mine in 95 and noticed one night that all the lights fluctuate, or pulsate . It speeds up with the engine RPM. I checked all the ground connections I could find . Replaced battery cables . rebuilt the alternator, bought another rebuilt alternator .... and still have this problem. I haven't messed with it in years but now that I have found a decent website / forum, I would like to know if anyone has experienced this problem and what you found.

Thanks

That's a new one, I've never heard of that problem.
I suspect that it's a bad ground or something is arcing with the distributor.
Is your car all stock or has it been modified at all?

Its all stock . Its not a severe pulsating , but you can definitely see it . Every light does it at the same time.

Most likely a ground issue or an issue with the dash wiring.
There is a ground that is usually hooked up the speedometer cable behind the gauges, make sure it's connected properly.
