So here I sit trying to figure out someone elses car,69 satellite with most of the original wiring cut out of it and painless wiring to replace it (dont ask) and when we first fire it the volts are upper 13s but after a short time they start climbing and settle in a little over 17,what can do this?

My first thought was the reg,swapped it out and got the same thing,checked the way its wired and seems ok.

Oh this is a two wire alt.

We really neec to convert this back to factory wiring!

What you using for a alternator

Mine was doing that last year was a bad connection on the 12v on to the regulator so it though low voltage and kept it charging full. in my case I replaced the push on connector and that fixed it. could be where it comes through the bulkhead check the voltage in the wire to the regulator key on.

Course could be a short in the alt or wires too it!

Factory style two wire.

New twist,I just unplugged the reg while the car was running and the voltage didnt drop,killed the car,left the reg unplugged and started it again,voltage started climbing.

Bottom line,this thing is wired wrong and I am not sure what to check with this stupid painless kit in it.

Make sure the regulator has a good ground...


If nothing else, maybe try "hot wiring" the regulator to the alternator (by passing the new wiring if it is causing the issues) and see if it works properly ?

Pretty simple to hook up a electronic regulator setup..

Well then it's getting 12 V to one of the feilds and not coming from the regulator.

Test both field wires for voltage (guess it should have just one feild wire) unhook the one with 12 or more volts and it should be 0 charge then find out where that wire is getting it's
voltage sine the regulator is unplugged??

still may be getting voltage internally in the alt with a short??

69 should be this type with one feild internally grounded or as newer alts ground the one field to alt body

So if it is painless wireing does that update to 70 and newer regulator??

if that is the case is alt updated to a 70 and newer isolated field brush.

If it is then is the wire shorting the ground back to the regulator

If it still has a 69 style alt with one field internally grounded that could be the problem?

Hear is the instructions for painless for 1969 does use the newer style regulator so ignition on goes directly to one field of the alt and splits off to regulator.

Other field off alt (green wire) goes to the other post on regulator.

If this is grounded it charges full regulator controls or should control amount of ground to regulate how much the alt fields are energized thus output

So I pulled the alt to check it and found what you said,its wired for the 70 and up but still has the 69 alt in it with one field wire grounded.

Just back from the parts store,should know the results of the correct alt soon :-)

Cool after my last post a twister went up through the back yards here tore down trees scared the crap put of me never seen or heard anything like it as I ran to the basement. was over as quick as it started. no power for 4 hours some roof damage at neighbors 3 houses down. part of a tree down across the back of my neighbors house another tree split at the back of his property just over the fence. lots of trees down for the next 2 blocks.

Now back to the 17V I think the new brushes come isolated wher one now grounds to the case and you can just put two of them in and your good to go?? I think!

Glad your ok,better go wash your shorts

When we first got it back together the volts climbed right to 13.8 and stayed there,so I soldered some wires that we had been messing with and taped up some others to pretty it up,volts shot way back up.

Looks like one field wire being grounded may have fried the reg,replacing that later today to see where we are at but I think we have it.

You do have a 70 and up regulator?? and then use the diagram OZHEMI supplied above or the one in painless instructions page 9.

you may have to unwrap all the wires .

pictures i took walking around the block

Yes on the 70 and up reg and he bought the car this way,we dont have the painless instructions.

I put a link earlier to the painless instructions hear it is again.

So how you making out?

'70 & up flat reg with the triangle connector and 2 field terminal alt correct? If you unplugged the reg triangle connector & it's still charging then the alt has a dead short in the field circuit inside it or the nearby green wire brush assy or the green field wire from alt to reg is grounded one of which is makeing it full field (max voltage). Less likely that it is the green wire since the reg end of it is disconnected but check the loom along its' path. Even with the reg unplugged the alt field is still being fed fire from the blue wire to one of the alt field terminals & it's puttin out max voltage just like it would when a parts house tests it. That high of voltage will FRY your electrical system. Keep run time to 5 seconds max just long enough to take a reading on the VOM to see if your changes have got it taken care of

Gave up!
I am not spending hours tracking painless wiring through the entire car so we are doing whaf really needed to be done,tracking down all the original wiring and making it factory again.
He will have brake lights and turn signals again when we are done :-)
