Which colour wire is which in the MPIII eight pin cable ?
My MPIII throttle gave out when it's way to short wire
got pulled out. Not having much luck connecting a
MPII throttle ,cruise and brakes . I already had to splice additional length
into the 8pin cable as it was not long enough for my tandem.
How do I check with tester for the plus 5v wire ?
Are there any other simple checks to determine which wire is which
and/or if controller is fine ?
I tried matching the red ,white and black wires to those on a working throttle
but no result ...
thx steve

Hi Steve, I don't know what colour wires are used in the eight pin cable but here's a diagram that should show where the ends of them connect, assuming it's wired internally the same as mine:

To check the +5V supply, put the black probe from your meter onto the battery negative (-) connection and set your meter to a DC volt range that is high enough to measure your battery voltage, just in case you touch the battery positive (+) wire by mistake, and then use a pin or paper-clip held against the red meter probe to gently touch the +5V contact inside the 8 pin socket. Don't push the paper-clip/pin right in, because it could open up the metal contact too far, resulting in a very loose and poor connection when the correct plug is inserted again.

Another top notch diagram Alan!
I have not been in the forum much lately. Recent events some may have noticed brought me back out of necessity. Very busy time of year and I miss coming here. Really this is where I really enjoy my free time online.
Anyway I see I have missed out on a lot of things. I see a lot of new people have joined. That's always great!
But as I was saying I think you need a section in the user guide for diagrams you have sourced or created. It would be great for browsing and help full to many I am sure.
