More charging questions

[Tony g]

I thought I'd start a fresh post on my charging (not working yet)
My alternator/stator is the same as in gggGarys post No 53 https://www.xs650.com/threads/diy-reg-rec-5twins-and-jim.55842/page-3
My inner brush is grounded as per Gary's explaination.
When I attached my spare RD 400 rectifier AND joined the brown feed to the green (brush) it charges but obviously unregulated.
I bought a fiat style regulator next (2 wires green and red) Wired green to green and brown feed to red. Grounded the body. No charge.
Have I bought the wrong regulator or is it dead on arrival?Link to the reg I bought https://www.ebay.co.uk/itm/183682730862
Bike and engine are pre '79
Cheers
Tony

I'd return it under eBay's buyer protection policy. If it charges with brown connected directly to green then it's not a problem with your bike.

I've only used the three wire* regulator so I'm not in a position to comment on that particular regulator. Unfortunately the Lucas UCB502 unit I used appears to be unavailable now.

* red, green, black.

Yes I was hoping to see an earth tab on the bolt hole like the one in the big thread (Jim maybe). Just need to be sure its the problem ie the correct one. Theres a Bosch RE 55 on the bay I might just get that instead (its NOS) in a box

You can return it no questions asked as far as I'm aware under eBay's buyer protection policy.

If you're certain the body is 100% grounded then it's likely dead on arrival anyway.

(I assume there's no voltage at the live brush when running and the eBay regulator is fiitted and the slap test will fail).

TBH I havnt checked V at the live brush I'll do that next time i'm running it

The regulator in your pics above is a type 'A' regulator. It regulates by grounding the green wire, with 12v to the rotor is supplied by a splice in the main harness.

Your '79 bike uses a type 'B' regulator. It regulates by supplying rotor power out on the green wire.

Does anyone sell regs as type A or B ? I'd never heard the phrase til on here. So will a type B have 3 wires?

would this Bosch one on ebay also be type A? (2 terminals) https://www.ebay.co.uk/itm/187376919995

For fun I asked ChatGPT for a recommendation.

"The Bosch RE57 voltage regulator is classified as a Type B regulator. This type is typically used in various automotive applications, particularly in older vehicles, to regulate the voltage output from the alternator. The RE57 is known for its specific voltage setpoint, which is generally around 14.2 volts, making it suitable for maintaining battery charge without overcharging."

Worth looking at further. It says RE55 is type A.

Due diligence required.

 

[Jim]

Yes, a type B will typically have 3 or 4 wires. If it's two wires (terminals), it's most likely an A

Yes, quite similar to the one I linked to near the start of the thread. That looks fine too.

Ive never heard of chat gp lol Thanks

Yes, a type B will typically have 3 or 4 wires. If it's two wires (terminals), it's most likely an A

If its 4 wire is the yellow the 4th and can it be connected to the red as Ive seen in earlier posts (possibly by yourself?)

It also says this about type B

Type B Voltage Regulator​

• Field coil receives constant battery voltage (positive).
• The voltage regulator controls the ground (negative connection) to the field coil.
• When the regulator completes the ground path, the field coil is energized, and the alternator produces current.
• Regulation is done on the negative side of the field circuit.

Which is wrong isnt it? Type B controls the live not the ground. What a rabbit hole lol.

Yes I get that. I had seen many of your great posts Jim and I thank you for your input(s) Problem is no one sells regs as type A or B and I wrong assumed the case could be the 3rd wire (ground). Ive ordered another and I'll keep this one in case I get a later bike. I'll keep i the "useful" drawer for decades lol

I did say I asked for fun. And that more due diligence is required. It's scary that this technology is being punted out there as the next industrial revolution when it's more stupid than intelligent.
