Furuhashi Voltage Regulator

[santamaus]

Hey--

Been having a bit of power fluctuation and high reading amp gauge. I pulled the voltage regulator, but I can't see any adjustment screws (like the stock unit in the manual). Is there some sort of adjustment? All the solders look good, and have continuity.

The first and second pins have continuity with each other, as do the third, fourth, and sixth. The fifth pin has continuity with both of the first systems when you press the two springs down, and alternates between them depending on which spring goes down, so all the connections seem good. Could the resistor be bad? What is its rating?

I'm going to try cleaning off the pins and seeing if that helps, perhaps a little bit of corrosion or gunk in there is causing trouble. When the lights are on, I can usually drain enough to keep the ammeter from getting all the way to +15 (which is good, since it likes to blow a fuse about then).

Any ideas? As soon as the pictures get approved, they'll be in my gallery.

Thanks in advance,

Chris

NEW: 09/06/03 Sorry to bug you all with this, but I haven't gotten any answers, and so I might need to buy a new voltage regulator. So, new question--I have a '72 with a L26 swapped in. I'm fairly certain it's the original '72 wiring harness. Do I need a regulator from a 240 or a 260? Is there a difference between the two? Different plug/activation or cuttoff current?

Thanks again,

Chris

Ok... cleaned all the contacts, and no difference.

I took the cover off, and watched it while the car was running. There are two electromagnets in there, one on the bottom, the green one, and the one on the top, which is copper. The top one has the little flap that allows it to contact twice for some reason.

Left to themselves, the green one does nothing, and the copper one stays shut, regardless of charge voltage (which increases with engine speed), or anything else. If I manually close the green one, the copper one opens, and the voltage across the battery stays constant.

Thanks for any help,

Chris

Finally got the pictures up... any ideas?

Thanks,
