Lucas voltage regulator adjustment! Mart's 100E part 72! (2410)

- Hello! Welcome to Mart's Garage. In part 72 of the 100E Anglia resurrection: While I fixed my charging problems by swapping the regulator I felt I needed to see if I could adjust my original regulator to give more output. Armed with the original workshop manual, I muddle through it as usual and gain a better understanding along the way.
I Hope you enjoy this offering. Don't forget: Keep it real! Keep it cheap!
Thanks for joining me once again in Mart's Garage.
Hi Mart, now that you changed the belt and adjusted the tension, I would keep an eye on the water pump. As it may have an impact on the water pump bearing. But a good result on the charging system
Most interesting and informative, should give you confidence in the charging system, when you venture on those night runs.
Love sound of engine running👌
The voltage between terminal D and earth (terminal E) is uncontrolled dynamo output, as the revs increase it could go as high as 18V. The output from the regulator, terminal A (ammeter = negative) and (earth = positive) is the adjustable voltage, I usually got good results setting it between 13.8 and 14.2. at fast tick over. This reading should remain constant, not increase with the revs. Remember the dynamo RPM is higher than engine speed due to the difference in pulley size. The other screw at the back sets the cut in speed. This prevents the battery draining back through the dynamo when the engine is stopped. It can be set to connect when the engine just reaches tickover. But if it ain't broke don't fix it!
good vidio we used to call lucas elec the prince of darkness I still do I had a BSA and an mgb lots of practice.
i remember back in the mid 70s i adjusted voltage regulator on my Austin A35 before heading on 100 mile trip well that night in the middle of nowhere. she died, i had over adjusted and killed the generator, she run on battery until that was drained , fun times, cheers the fan belt just needed some duct tape
Another interesting and informative video. I watch these religiously. Keep them coming Mart!
Watching this from the side of my swimming pool in northern Thailand. It must be cold over there to be wearing that Woolley hat in your garage!
great result, fascinating as always 👍👍👍👍👌👌👌👌
I think the old BELT HAD A FEW MORE MILES IN HER MART 😂
Great job as usual 👏👏
As always👍
Another enjoyable video! Take care
hello Mart, great video, as i am very bad with electrics, by following your instructions i could regap and adjust the volt reg on my 105E engine (which is in a Terrier Mk2), thank you
Hi Lawrence. Glad you found the info useful. As long as you can keep the contacts clean you should do ok. I googled the Terrier Mk2 and it looks like a fun little race car. You say 105E. Did it originally have a 100E engine or is yours a later version?
Great job Mart !.....very informative video.........Mark
Excellent. You've peaked my interest, I need to go find some theory on these. I'm wondering how it controls current?
Super glue on fanbelt Mart lol
"Cracking upload mr Mart!
Thats some head work mart rather you than me are you regulated lol.
Nice tinkering....not sure about the hat.....makes you look like Deputy Dawg!😂
i am a skilled mechanic of 50 years
A note to all readers if a BATTERY IS OVER CHARGED OR OVER AMPED IT CAN AND WILL BLOW APART I HAVE HAD THAT HAPPEN WHEN REGULATOR FAILED AND CHARGED ON FULL CHARGE
I suppose those regulators were originally set on the old style batteries. So they’ll be different on a newer type?? Or doesn’t make any difference 🤔
Hi Mart, from some of the shots in your video, have you put the rest of the interior back in (or have I missed the episode covering that)?
Hi Steve. I have put the seats and some trim back in but haven't edited up a video yet. Thanks for watching.
Hello Mart, the fine adjusting of the "contact breaker coil & screw" went well, but hat about the other coil on the reg which closes when the engine is running and opens when the engine is switched off to stop the charge from the battery flowing back the wrong way?
I just left mine alone except for cleaning. That bit either works or doesn't. Not working can be quite catastrophic.
looks like it wonts a new fan beet mart grat blog a gen mate gary from crewe 👍👍👍👍👍👍👍👍
you should be charging at 14.7v mart
Perhaps on an alternator
Hi Mart, a good video. I have a Midget from 1967. Would you give me your manual via pdf...because I have no information. Thankyou you for your help. Kalli
Hi Kalli. Thanks for watching. I googled MG Midget workshop manual and found the following link: www.spritespot.com/referencedesk.htm#Workshop_Manual Hopefully you can get the info from there. Cheers! Mart.
do you have knowledge of Wilson pre-selector gearboxes?
Hi Lawrence, no, I'm sorry, they are a mystery to me.
Be careful no charge no danger over charged BIG DANGER BATTERY CAN BLOW APART AND ACID CAN GET IN YOUR EYES AND ALL OVER YOU JUST TRYING TO HELP SO WE ARE ALL SAFE.
Hi just for your info. Maintenance-free or sealed gel batteries cannot explode as there is no liquid acid present, and the chemical makeup of the battery differs from that of the lead-acid type. No hydrogen gas is generated, so there is no risk of a spark igniting anything. If Mart has fitted a modern battery there shouldn't be a problem, however it's not good to have a high charging voltage. I believe it should be in the order of 14.4V. But because this is a dynamo with a somewhat crude regulation system I guess the charging voltage may vary quite significantly and thus also the charging current.😏
@@brucepickess8097 you are right should be 14' 7v
@@brucepickess8097 Sir listen just for your information that information was a general warning ⚠️ for the general public thet probably are not a chemist or apparently an expert in battery technology it was a general warning so they can consult with a professional like you what i do know IS that some battery can explode I owned a battery that I purchased from sears iyears ago my voltage regulator malfunctioned and said battery blew all sides apart and all that was left where the top and bottom of the case on a Friday and untill I took it to sears on Monday it would still start the car what the exact 💯 chemicals inside that battery only people like you would know i did not want it to happen to regular people it was not intended to warn them or you of the battery's than can not hurt them SIR it was to be a warning of said battery's that can just for you to understand i.guess I could give them other warnings like electric vehicles but I would be wrong again so I will let you help them SIR AND LASTLY SOME PEOPLE SHOULD CAUTION ⚠️ TO HELP THEM FIND EXACT CHEMICALS INSIDE THAT THEY ARE DEALING WHIM A COMPOUND THAT WONT HURT THEM SIR
