Dim headlights, slow indicators etc

[boss429kiwi]

Hi

On my Superbird, the head lights are dim, indicators are slow and my alt gauge flicks around.
I've checked the groundings and all looks ok.

Engine cranks and starts fine.

Any other suggestions.

Cheers

Hi,

What you describe is normal at engine idle and a heavy load on the electrical system. The alternators of the day did not produce much output at engine idle. Things should improve as engine RPM's increase. You might want to put a voltmeter across the battery and measure the system voltage. You should see 14.0 to 14.4 volts at higher engine speeds, if not you have a charging system issue, bad alternator, regulator or wiring.

Cluster connections all clean and tight?

As Pete said , this is common at idle. I do some country driving and at a stop sign at night with headlights on , brakes applied and turn signal going it was like a hamster in my headlights holding a birthday candle. I added relays. Power right off altenator , switch works the relays. One for low beams , one for high, Mounted mine right on rad support .  Not a factory thing but got good lights now.
