As always, excellent, thanks for sharing. Cheers.
Thank you! Cheers!
A problem I've often seen with generators that haven't been rebuilt is when trying to adjust the third brush the old paper insulator will break and "Earth" the brush which kills the output, then some get frustrated and replace it with an alternator... It's always best to make sure your brush carrier is in good shape before adjusting it. I have a grounding wire attached to the generator post with a toggle switch near the steering column so I can switch off the generator when I'm on a long drive. I run LED lights and turned the 3rd brush way down and have noticed the output seems to self regulate. Right after starting it will charge more then after a while the charge reduces from 3 to about 1 division on the ammeter as the battery voltage is back up and electrically pushing back against the generator.
I have noticed the same; those old paper insulators are fragile with age. Neat idea about wiring-in a generator grounding wire with a switch! I like that. Thanks for watching.
Geez, how did I miss this? Just subscribed, now maybe I'll actually learn something.
Randahl, thanks for subscribing! It will be a pleasure to share my occasional antique-car videos with you. I hope, someday, to be as comfortable on camera as you are!
Fantastic video. So useful. Many thanks.
It's my pleasure. Glad you found it useful!
@@flivverchannel I'm currently restoring a 1942 Universal Bren Gun Carrier which is powered by the Ford Flathead v8. It also uses a 6v generator which I'm attempting to recover to full serviceability. It's so difficult finding any information on this topic.
@@chalkster4723 Inyeresting! Check mtfca forum, lots there on 6v gen too
What an excellent video and I really appreciated the amp meter animation. I have a 1938 Prefect with the 3 brush generator and have been struggling to keep the battery charged but you have shown me where I've been going wrong. Thanks.
Awesome! Cheers.
Have you used a fuse in the field wiring to protect the generator in case the generator wire becomes broken or disconnected?
I haven't, but that sounds like a good idea. Do you have details?
It would have made a lot more sense to run the field coils in series with a rheostat on the dash so you could adjust charge current on the go.
👍
There was an accessory, one called the "Majestic Generator Output Control" that used a Carbon Pile rheostat to adjust the field.
I wanted to ask sir does that short generator work also on early alternators? I recently acured lot problems I know those old 12si Delco alternators are trobeo some their diodes fail ,voltage regulator fail often,they back charge at low rpm even more if hv ceramic capacitors are present the starting charge gets swaped to around 2500-3000rpm ,how ever recently be me acured some thing unusual relays cinde of arced true me wire harnest I must some how arced the trailer cabel to the bumper rosty metal and aperantly because of blinker relay I got shock true me car body it was nearly identical to dual ignition.
So in fact me baterry stayed alive longer at colder weather so I wondered me self what that was about ?
Why does the lead acid baterry 12v negative ground refuse to discharge baterry It nearly looked like it prefered cold weather for some reason?
Were there any efficient way to send full dc or ac power to ignition coils back in the days with out getting shock from the alternator power?
I culd not finde any thing related to this subject how to use ac full alternator or generator power with out destroying baterry or to prevent electric shock true the car boddy .
I hope for some help .
Europ version cars do not have any usefull info about that subjects and I have realy hard time finding nice replacment ignition system for me 4 pin gm ignition module with e core type ignition coil Im realy anoyed with that thing any advice where to finde advancing/retarding circuets who fit for GM/Opel engines like advance/retard levers in cold mornings Im dead meat engine refuse to start
I do not know if an alternator can be 'grounded' to disable the field coil in the same way. Sorry, I just have not spent the time to learn about alternators, yet. I wish I could help you more.
No, if you ground the output of an alternator it will only burn off the wire. You'd have to disconnect the field power. As for the rest of your questions... no idea, your modern car should be doing all that automatically. This is a Model T Ford channel.
