Lssv cucv

I thought it was an isolated 12v like the cucv?

its a 24 volt alternator single wire . GM manual had part number for it and spec.

I lost all my saved info when my laptop crashed.

My 24V alternator has a 12V regulator that's burned out. Any idea where to get a 24V regulator for this alternator?

FYI:
Battery voltage with the engine off for the 12 V passenger side battery is 12.74 V. With it running it’s 14.58 V.

Battery voltage with the engine off for the 24 V battery on the driver side is 24.80 V. with it running it’s 29.35 V.

Alternator voltage with the engine off driver side alternator is 12.64 V. With it running it’s 14.62 V.

Alternator voltage with the engine off on the passenger side 24 V alternator is 12.20 V. With it running it is 29.31 V.

The alternator that is putting out 24 V has the marking stamped on the case for a 12V. The alternator has a part number stamped on the case showing 12 V, also 105 A.

I will probably open up the back of the alternator to see what 24 V regulator is there so I can order a spare.

Are any of the alternators isolated ground?

Not sure.
The passenger side alternator does have a ground wire that goes to the negative side of the designated, 24 V battery on the driver side.

I converted my M1008 to serpentine belt. I couldn't find a CS130 alternator in isolated ground so I drilled out the mounting holes and installed plastic sleeves and Garolite washers. Those look like CS130 alternators in the LSSV.

Did you have 2 alternators? Like a regular cucv?

I have a regular CUCV, 1986. I bought an eBay 6.5 from a 2001 C3500 truck because it had most of the brackets to support dual alternators and AC. I still have dual alternators now. There is a company that makes pigtails to plug the 27SI connectors into the CS130 so everything else was plug and play once I isolated the passenger side alternator body.
