'98 748 - Which way around do these wires go into this connector (battery tray)

Discussion in 'Technical Help' started by jammy_basturd, Nov 29, 2012.

  1. I *think* it might be one of the rectifier/regulator connectors. But basically I disconnect this connector without realising there were two spade connectors and that both wires were red (and then yellow on the battery tray side). I can only hope that since both wires are the same colour, it doesn't matter which way around they are connected?

    Also, I guess that one half of the connector wasn't originally spade connectors? If not I think I may cut out the original connector and replace with a AMP Superseal connector, as these two connectors are a bit open to the elements anyway.

  2. Reg/rect wires woulld be yellow, yes! Follow them up from the flywheel case & check? Make sure the AMP connector will carry a LOT of juice...
     
  3. Yep regulator cables, looks like they have been upgraded, the connector needs to carry at least 35 amps.

    Can connect either way round.
     
  4. if 2 yellow from regulator then either way is ok j.b. as they are 'A.C.' output from generator.
     
  5. Thanks for the replies guys. Luckily one of my mates works for AMP, so getting a connector to carry enough juice (woof woof), won't be a problem.

    One last problem I've just realised, is that there are two red wires, and three pins/yellow wires. :frown:
     
  6. great.. you need a Denzil now as I would have to confirm with a read -up. If you can safely run bike with them disconnected and then check output with meter set to 30-ish volts ac you might find that only two wires will give you this output. Hopefully an electrical technical will be along soon.

    EDIT i've just seen from picture it's the regulator that has the 3 wires so white flag time for me now, sorry.

  7. I recently did all this gubbins on my bike. I chopped out the white connector and soldered the wires.

    Black and red (+/-) direct to battery, live via an in-line 35amp fuse.
    Made a huge diference to the charging voltage.
     
  8. Just read on another forum (sowee) that I can connect the two wires to any of the three pins. Hopefully that's correct?
     
  9. Well after my first hour and a bit on the bike this afternoon (which was incredible), I'm happy to report that I either guessed the pin combination correctly, or indeed it doesn't matter which wires go on which pins!
     
  10. JB thanks for reporting back to let us know.

    I was pretty sure it would make no difference using a 3 phase rectifier, but I was not 100% certain and therefore didn't post. The Internet has enough 1/2 baked idiots answering threads that they know nout about, without me adding to the chaos

  11. No worries.

    I'll report back again if my leg catches on fire due to a smouldering rectifier connector.
     
  12. If in doubt get the voltmeter out...:upyeah:
     
  13. Similar thing happened to me with my CBR6RR, rectifier died and was sent back for a warranty replacement. New one arrived but the plug that goues into the bikes loom wasn't wired, I had to do it myself. Simple job as the wire spades just pushed into the plug, but there were 4 wires, 2 red and 2 green, and no instructions. It was obvious that the red went one side and the green the other, but I wanted to make sure it was safe to fit the pairs or wires either way. A call to electrex confirmed it didn't matter.
