- Is your battery not charging? Do you think it's the alternator? If you have an older vehicle with an external voltage regulator, you may be able to save some money by just replacing the regulator. In this video I show you how to test your alternator to make sure the problem is the regulator, and also how to replace the plug if it's beat up and corroded.

Dude. I was just in the side of the road and something between last week and today happened in my 85 Ford F250 w 460 charging system. It’s possible my ignition didn’t close all the way and drained my battery. I tested battery and it was 8. I had to use jump box. Started and checked voltage. It was around 12.5. Started to drive to town to put a little charge and go buy a battery. Truck lost power on the way and that’s that. Charging the battery now, hopefully it takes the charge. I then will do your voltage regulator test to see if it’s that or the alternator. Thanks for posting this man. I asked the parts store if there was a way to do this and they said nope!
Glad it was helpful! Yup this is straight out of the Ford factory service manual, so totally legit test!
@@rednecklite follow up. I performed the test. It didn’t go shooting sky high, but it began at 12 and then 12.2, 12.4 and climbing but it didn’t jump up to 13 or 14. Continuing to charge battery and purchased a new volt reg. $45 Standard. Made in China of course.
Thanks so much! I have a 71 mustang a that had no power and you saved me a lot of headache.
I worked at a generator and starter repair shop in the 80’s and we used piggy back regulators on older fords that the customer didn’t want to get into the cost of repairing the wiring harness. The worked great and made the alternator a one wire hook up to the battery. I’m pretty sure the are still available at local rebuild shops, most of the older vehicle aftermarket oem parts produced today are junk .
Thanks brother ! My truck has been sitting since 2020 ! And just started to wrench on it again! One reason it sat was it kept draining my new battery but regulator never crossed my mind I replaced the alternator before it sat and then the world took a crap and I started a family lol but I wanna get my 81 f100 back on the road to cruise with my lil boy in the summer . I will be using this method to test the regulator thanks !!
Glad the video helped! I have my great-grandpa's 80 f100 I'm working on myself. Gotta keep these survivors on the road.
Thank you very much!
70 mach 1, Windsor-im on my 3rd regulator, 1st one new China, last 2 off ebay (used vintage). I may look into a custom vintage style the way things are going. Thank you again!
It's a good ideal to solder and tape the wires crimp ones can cause problems
Thank you very much! This helped me a lot with my 83 F150.
Thanks man the detailed explanation was so helpful
I have a 65 Mercury Comet Caliente this is exact what I needed to watch. I was going to replace the alternator then I did some wire tracing and my voltage regulator looked like a melted 💩. Thanks again for the video. 🙏🏽
Very good video!!
Good stuff!!
I’m wondering if I have the same problem. If I plug in my alternator on the solenoid I can’t put the battery in because it shoots heavy sparks
Why when I jump the terminals battery goes from 12.2 down to 11 why would it go down rather than stay at 12.2 if alt is bad ? Thanks
That might indicate a short circuit- voltage goes down when a load is placed on the system, still an indication of a bad alternator.
