Volt Reg capacitor

[Merlin68F100]

There is a capacitor or condenser connected to (was connected) my voltage regulator, when I swapped out to a new regulator the connection for the condenser broke. The wire looked like a fused link almost. At any rate I do not see any issue without having this thing in the mix. Does anyone know what its reason for being was? Noise suppression for the OEM radio is my guess.

the one on the coil does the radio thing. i forget what the one on the regulator does but i think it has to be there in order for the charging system to work. im probably worng.

I am charging, so it is not required for that. It is between the charging system and ground so that should be a clue.

It was for noise suppression as the old (original) voltage regulators have points in them that would cause noise on the radio. The new voltage regulators are solid state so no noise issues.

[fordman]

so you need a condensor on the coil AND the regulator to get rid o fall the noise for the radio. except for the electronic regulators?

[Thunderfoot]

Yep, those points in the old style regulator are opening and closing making electrical noise. the condenser takes the noise off the line.

I guess now I know why my truck never had those and my friends truck had em. My came radio delete when new. I learn something new here everyday.

never have had one on the coil besides the condensor in the distributor itself. my Radio suprressor on the volt reg is 38 year old original more thn likely. Just this weekend on sat afternoon, my chargng system quite. it had two thngs wrong for sure,

Flash rusted/coroded terminals, cleaned them the battery charger at the o'riely's got her charged to 12.3V Running with a voltimeter/multimeter i was only getting 12.6 out of the alt. The alt itself is fine but the volt reg was dead.

To be on the safe side my 100 amp alternator from an 88 F or E series with a new volt reg went in(same volt reg the VR 400 that was used for years. it seems to be charging now. I'm not sure but i know what is working so from there i go.
