Ok thanks for the info….my new readings are….at a high idle both the regulator and battery test at 7.0 to 7.2 volts they appear to be testing the same amount of voltage…. At same high idle the generator is testing at 7.8 to 7.9 volts. According to those test instructions this is pointing to a bad regulator which I ordered yesterday. My ammeter needle slams to the right and to the left based upon idle..it gets stuck in both full and empty positions until i tap it and release it…should I do any tests with the field wire or do you thinks it’s the regulator…thank you!!

Ok! I assumed it was positive ground cause of the age…I’ll go check it again now tks

Terrible pic but was directions regarding all issues wi5 my generator. I started today identifying that the generator is a b type. Then starting with a battery measuring 6.2 volts the car started up. Then began testing..hard for me to determine high idle so I was just accelerating a bit..when testing at high idle I could get Around 6.6 volts at a much higher acceleration I could get it up to the 7.5 volts…but it was Erving high….testing at idle I’m always getting a slightly lower reading at the regulator then I do at battery and starter as I’m testing the battery is draining…after 30 minutes at low idle I’m at 5.91 at battery/starter and 5.85 at batt terminal at regulator….when idling I’m getting around 5.8 at arm terminal and that too will go up to 7 plus if I really accelerate….last it instructed me to conduct field test as the same advise I got here..it said to turn car off and remove field terminal wire from regulator ..restart the car to high idle and ground out the detached wire the voltmeter was grounded at battery as instructed and positive was attached to arm at generator for test….when I grounded the field wire I get very little voltage ..not even 1 volt..more like.
.5…so I assuming that’s a generator issue? I don’t know…I’m getting good ground at generator and regulator..hoping this will help trying to show what’s going on…I had to stop as it overheated sitting at idle for an hour..thats never happened before..but I don’t think I’ve ever let it sit that long at idle

Edit…I realized the field was not secure on the generator end when I did test so will try again when battery charges
Edit,.meant to say I have a type generator not a b

Edi…so I completed field test again getting0..5 vo,t then up to 1.2 volts when grounding field wire removed from regulator..no idea what’s going on

How much higher should the resistance be?

Looking From the front of the vehicle looking straight at pulley the generator is spinning to the right..

I tried but it won’t let me post video

Ok did resistance test on two lower contacts on regulator and when I opened either of the it raised ohms significantly..was barley any reading and hard to do when closed contacts…it would start at a number and go down to almost 0… I did the resistance on the generator and now it’s closer to the same where fld to arm is 3.6 and to ground is 3.7 or 3.8 ….?but ground is still slightly higher I guess

Ok well I tried it again now the generator is spinning much faster and when I ground the field it slows down which is what I saw on the video. However, I see very little jump if any in voltage when grounding the field..a couple times there was a quick glimps of a high reading like a blink when I was removing the jumper wire from ground but mostly stayed the same voltage..also I noticed my ammeter was now stuck in the discharge position and after I tapped the glass the needle returned and it looked like that was affecting the power going to generator?? I will attach video…the generator was reading around 5.5 with direct power to it but the battery is getting drained as I’m working on it…maybe goes up to 6 when field grounded tks in advance!

Did another test from Autolite where I removed belt from generator and applied battery power to Arm this activated the motor and runs smoothly…with motor operating I then grounded the field terminal ..doing so is supposed to alter the speed of the motor which indicates brushes working..in this video it clearly shows motor speed changing when field is grounded…when I applied ground to field nothing changed at all….this test was easy for me to understand so I tried it…not sure how accurate it is ..
