Reg / Rec

[Al]

Pretty sure my new RR has fizzed itself.
Not sure if it was me or a problem with the wiring (caused by me probably)

Have been getting a healthy spark when connection /dis-connecting the second battery terminal with ignition off.
It measure full battery volts between the isolated battery terminal and the loose (unconnected) wire with ignition off.
My old RR (still functioning) when substituted, measures 1.3 volts between the terminal and the loose wire, which is probably not correct either!
Have ordered a new RR but keen not to see it go the same way.

Any idea what it is i am seeing by measuring full battery volts(12.7v) or 1.3 volts (for the old RR)

Disconnecting the RR from the bike was the only thing that would stop this 'leakage' (continuity) when i went round it in turn, dis-connecting everything and measuring as i went.

The only way you're going to see full battery voltage when connecting between the battery positive and the positive feed wire is for something on that wire to be connected to the bikes frame (negative).

Code: Select all

               Battery

    Frame                   Voltmeter

If the RR is the only thing that stops this then I think you've found the culprit.

Thank you ruffle, thinking about it today, i came to the conclusion that what i was measuring is a direct short in the RR (new one) and a less than full short in the old one (1.3 volts).
There is a positive and negative wire to the RR and these must now have become internally fused.
It still reads the same if the RR is isolated from the frame so i suspect an internal route.
The question remains for me; who dunnitt
I will give the new one a good looking at when it arrives and see what that measures using the same method!!!!
