Alternator voltage regulator
« on: September 11, 2023, 09:47:46 PM »
I have a spare regulator from my Volvo parts and it looks exactly the same, except it has a capacitor soldered across two points.  My stock regulator is at .2, while the Volvo one is .395.   Is it safe to assume that I can unsolder the cap and use the Volvo one?

Still assuming, huh?  :laughing4-giggles:
I wouldn't say they look exactly the same, but be bold and let us know how it works out.

One unimpeachable source indicated Volvo regulator  244332 is a sub.

I'm going to go out on a limb and suggest that the capacitor on the Volvo regulator is for noise suppression and won't affect alternator performance running the electrical system.

I'm going to go out on a limb . . .
If the limb breaks, your Brick will still be charging the battery.  :laughing1:   Seriously though, give it a try, Lbx. A good outcome could help others. Any legible numbers on it?

No numbers that I see.  Im pretty sure I pulled this from a Volvo 240 out of a junkyard, and Im pretty sure the 740/940 has the same alternator.

Id be wary of the capacitor because of its age. It could be defective. Id see if you can remove it unless you can test it.

I unsoldered the cap and put the regulator in.  Works great.

For those of us not hip to electronic patois, cap refers to the capacitor indicated in Reply #7.
