Re: Another battery charge thread

Yes, you may have to piggy back on one of the yellows. If the first yellow wire doesn't give you the correct readings, or no reading on the tach, try the other yellow wire. Doesn't hurt anything to hook it up to either yellow wire.

NOTE: If you are using a universal regulator, the wires may not be yellow, so I just want to clarify..... you hook the tach lead up to one of the battery charging stator leads which may or mat not be yellow.

Re: Another battery charge thread

yeh, thanx PNW.

I have messaged the seller of the below item on ebay to see if he can comfirm what Jiggz susects below anyway:

That definitely looks like an aftermarket Universal rectifier/regular unit. Here's what I believe it looks like although the gray wire is now a black wire but functions the same.

Sports Parts Universal Regulator/Rectifier 01-154-16

Ive exhausted most avenues locally for a universal one, looks like I have to resort to Amazon for the above, the same seller doesnt seem to ship internationall on ebay strangly enough.

I guess the fact we get very little snow in OZ means snowmobiles arnt so common LOL

Re: Another battery charge thread

Much appreciated Jiggz, that one is clear about the black wire being earth.
Have u actually tried the previous one you linked or just suspect the blackt being a tacho output?

I actually have an identical unit on my system after my OEM selenium rectifier burnt out. The black wire is negative or "earth" or "ground" AND NOT FOR THE TACH INPUT SIGNAL. The tach signal will have to be taken from one of the yellow wires (AC input). The tricky part of the unit is that you need to make sure the body or the casing is also grounded for the unit to operate properly. And this is usually accomplished with the mounting bolts, which you just need to verify after installation.

Re: Another battery charge thread

Thanx Jiggz, I assume its been fine?
Ive found a way of getting this very one delivered to my door for $60 AU:

Amazon.com: Sports Parts Universal Regulator/Rectifier 01-154-16: Automotive

But now beginning to question if I should pay the extra for piece of mind and buy the CDI brand one:

Mercury / Mariner Voltage Regulator: 194-5279

Probs get it delivered for $150-$200 , but that's a lot more $$$ for something that may function no different to the cheap one. After all, CDI only offer a 1 year warranty them selves

Probs the same thing in a different box aye?

edit, having said the above and some further digging, every single type of reg/rec has died at some stage it seems, here is a thread claiming CDI brand isn't what it used to be:

Re: Another battery charge thread

Well, not sure Ive had success.
So I finaly got my Req/rec from Amazon, wired it up as per this:



Photo isnt clear, but the black wire is earthed as is the body of the new reg

Ingntiton on, fully charged batteries:





Start engine and the Multimeter bugs out and I get a whole lot of jiberirsh come on the screen.
Volt meter doesnt change in dash, revved up to just over 2000rpm on the muff with the fast idle, needle didnt move....
Intrestingly, the tacho worked fine up to 2000 rpm regardless which yellow I spliced the grey into
I even checked the AC output from the stator, again at 2000rpm:



The only thing I didnt check was the voltage at the batteries, but Im assuming thats what the voltmeter is showing me.


Has the conversion failed me?

Re: Another battery charge thread

The AC output from the stator seems low. I would expect to see more like 14 to 16 volts AC. Disconnect the rectifier/regulator and measure the AC output of the stator. Also may want to replace the one bullet connector on the yellow stator wire that looks a bit burnt. I see many of them that looked like they have been over heated as do yours. I replaced the bullet connectors on my charging wires to regular soldered eyelets and a terminal strip.

Re: Another battery charge thread

The second pic is the AC out put of the statorwith the reg disconnected, its just above 12volts at idle, and and does increase with revs up to about 14volts at 2000rpm

Re: Another battery charge thread

Well everything seems to be hooked up correctly, AC output from the stator looks to be normal.

Make sure your battery cables, positive and earth are making good contact and you don't have corrosion on the underside that is creating resistance. Also make sure the battery has a good charge. Make sure that you have continuity on the Red wire between the Regulator/Rectifier and the battery connection lug or post on the starter solenoid.

If everything checks out, I would take her out for a spin. I'll bet that once you get her revved up to 3000 RPMs or more for a minute or more, you'll see the voltage increase to 13.5 - 14.5 volts. If not, then I would suspect that the Regulator/Rectifier that you purchased is not functioning correctly.

Re: Another battery charge thread

All the cables and terminals are brand new, batteries where fully charged and have been load tested as ok.

I will take it for a spin before admitting failure, but I was under the assumption that whilst the motor is running and I check the voltage output from the Rec I should be getting some kind of DC reading on my meter, not jimberish

Re: Another battery charge thread

Your assumption is correct. You shouldn't be seeing jibberish on the meter. It should be reading DC voltage. Just a long shot but try reversing the two stator leads that go to the reg./rect.

Re: Another battery charge thread

It would appear that your new reg/rect is defective. Not the first time it has happened.

Re: Another battery charge thread

Yes just give it some more time and see if it starts to work correctly after a longer period of time. At this point you have nothing to lose.

Re: Another battery charge thread

I wish you had taken a pic of the jibberish reading on the voltmeter. Anyways, as you have mentioned, there should be at least a battery voltage reading with the engine running from the output of the reg/rec unit and NOT JIBBERISH! If the regulator is working correctly and only if rpm is above 2500 RPM, the output reading should be around 12.75~13.5 VDC depending on the charge state of the battery. The lower the charge state the higher will be the read output, remember there is a regulator on this one. While you are testing disable or turn off all aux equipment until you verify the regulator is working properly. Also, verify proper grounding or "earth" using a ohmmeter and should read less than 1 ohm between ground wire and earth and also with the regulator case. And finally, check make sure no circuit breaker is tripped.

Re: Another battery charge thread

When I say jiberish, all the screen turns into 8888888 and all the symbols illuminate.
No other aux items where on, and my raised idle lever only raises revs to 2000RPM.
As I say, the volt meter on the dash doesnt go abuve 12volts either.

I earthed the case a few diffrent ways, non made any diffrence, but I will check the resistance aswell.

I will start the thing again 2morro ( saturday here in australia) , let it idle for longer and trick it inot revving higher and take a picture of this "jiberish", plus check the voltage at the batteries and see if it raises as I increase revs.

Thanx for your help guys.
