    That could be awesome mate! I imagine it would make it to Melbourne by Thursday/Fri.

    How would I check my reg/rec with a multimeter? I wasn't sure what to do with it once I had it disconnected. My only hint to go off that it's buggered atm is that the battery was hitting over 17v while revving a tiny bit.

    Didn't even think of bike wreckers - could try calling a few tomorrow, but it's a needle in a haystack situation I'd say..
    Such a bugger to be stuck with the deadline of Friday. Hopefully I can call up and bargain a few more days on the phone tomorrow..I was meant to go away for a few days and this little incident has stuffed up my plans big time.

    With that voltage going to your battery the reg/rect would be the first thing to test.
    Have you checked the black earth witre with the ring terminal is going to a good earth?

    I have forgotten the reading's it should give across the 3x white wire's, i'll have to look it up tomorrow

    I'll check that tomorrow morning. I'm 95% sure it was for the test I did a few hours ago, and I'm a bit apprehensive about starting the bike again before I know I've got a decent reg/rec. Let me know what the readings should be once you know :) I'm not quite sure what you mean by 3x white wires though, as the reg/rec only has 4 metal prongs..

    G'night mate, thanks for taking the time to help me out. I'll be up first thing tomorrow.

    The reg/rect has 3 white wire's going to it and a red wire, then there's the black that goes to earth.

    Ah yup, you're correct. So I'd be testing the prongs (once I've removed the reg/rec) according to what colour it has going to it when plugged in?

    Yes I have two spares although I'd have to dig them out. Where in Melbourne are you @james1234 I'm up near St Albans if you come up we can test and try another reg/rec and see where we get to.

    Otherwise this:

    Hey mate! I'm in Brunswick, so not too far. I'm not sure if it's the best idea for me to drive the bike out to you with the faulty reg/rec or without one at all though..

    To do that test at the end with the reg/rec pulled out, do I use the bottom right corner as the negative terminal?

    I imagine already with the reading exceeding 17V yesterday that the rectifier is fine, but the regulator part is bad...

    Haha agreed. Would be nice not to have the pressure of having to get it inspected by Friday though. :aggressive:

    @joker I wouldn't ride out to you on the bike but it'd be great to come pick up a reg/rec if you can find one!

    Yeah to test the reg/rect, unplug it and set your multimeter to 20,000 (20K) Ω
    Looking at the reg/rect with the terminals facing you, put the red probe to the bottom left terminal and the black probe to the bottom right, write down the reading
    Next keep the red on the bottom left and put the black to the top right, write down the reading

    Now place the black probe to the bottom left terminal and the red to the bottom right terminal, write down the reading
    Then leave the black on the bottom left and put the red probe to the top right terminal, write down the reading

    The 2 reading's you get on your meter should be the same or close to the same
    If there is a big difference (over 8-10 Ω) it show's some component's inside the reg/rect have failed, a capacitor or resistor may have failed

    With the lead's reversed you should get no reading at all
    If you get a reading here, it show's that one or more of the diode's inside the rec/rect have failed
    Usually when a diode fail's it will blow out some of the epoxy potting (making a little bubble and sometime's causing a hole) that's there to waterproof and help stop vibration in the circuit.
    The diode can blow if a battery has ever been fitted with the terminal's around the wrong way, they can also fail due to excessive load's like trying to charge a weak battery, or from high current trying to move through corroded terminal's.


    It will pay for you to check the condition of your terminal's too if you haven't done so yet.

    You can buy some dielectric grease from Supercheap etc and use that on the terminal's to help stop corrosion
    Some place's like Repco, Autobarn etc have it available in smaller satchel's cheap too.
    It can also be called ignition grease or bulb grease

    The reading's you'll get should be around .19 Ω to .29 Ω, but can be a bit higher in some reg/rect's too
    Let us know what you get

    Hi!

    I got the following readings from the order you described:
    First number is with other colour bottom right, second number with other colour top right.

    Red in bottom left: 0, 3.33,

    Black in bottom right: 0, 3.33

    This is with the reg/rec probs facing me, black side facing up, multimeter set to 20k Ohms.

    Have the locking tab at the top of the reg/rect (think that's how you are testing it now ?
    Try it with your meter on 200 Ω

    My reg/rect is out of spec, 60Ω on one 100Ω on the other, sorry

    Yup, locking tab at the top.

    Thanks for taking the time to test yours for me.

    On 200Ω I just get one flash of a number between 20 and 100 for Red on the bottom left, Black on the bottom right, and then 0 for all the other readings....

    It's pretty odd - I imagine 200 or 20k is just the scale right?
