    hi mate
    if you remember you came over and performed some dark arts on my vf750

    well i connected the wires up...that was easy.

    when the bike runs those wires i used to elongate the alternator wires to reach the rectifier . they get very very hot.
    i mean HOT!!!!!!
    would that be indicative of me using wires that were too small or of a problem with either the alternator or reccy?

    the bike runs fine and as far as i can see the battery is charging(cant say for sure)

    cast me a spell from afar

    cheers oh wizard

    know i'm not Jon but hot wires normally means they're not rated high enough to deal with the current going thru them
    onwards and upwards and sometimes a little sidewards....

    What guage of wire did you use? What method did you use to join the elongated wire? What is the alternator output? As said above, sounds like wires are underspec'd for what you're trying to do. You should also check all of the connections to make sure they are clean and tight. If they're as hot as you say then a meltdown or fire is the likely end result.

    yeah, i suspect wires.

    i just used some from what i junked off the bike...they were yellow so colour coordinated.

    blade type connectors....oooh! how professional.

    Glad you got it running in the end.

    How hot is the regulator/ recifier??? Just check that isn't toasting as well. If so it could be that. If not, I'd guess you've used too small a wire. I'd guess you need 16 or 14 swg wire for the alternator.

    Paper clip! lol :

    Yea your wires are undersized thus the overheating. Get sorted ASAP else the wire in the sheath will fail eventually potentially causing alot more damage. Do a bit of digging and see if you can find the correct size required before ordering.

    Here's a guide:

    http://www.batterywholesaler.co.uk/b...wire_gauge.htm

    The lower the gauge number the greater the diameter of the wire = greater current capacity. Note there is a difference between SWG (Standard Wire Gauge) and AWG (American Wire Gauge). I don't know where your wires are but you need to know the maximum current draw of the circuit and use the right gauge wire. If your alternator output is 60amps at 12V then you would need 8 gauge.

    now we are getting silly.... swg, awg, 8gauge, alternator output .

    third party fire and theft - that'll do...i know nothing

    seem to remember when we had the kitchen done there was some earth wire that got pulled out....sorted....result.


    cheers guys.
    if you see smoke in the distance it'll be me

    Are you sure you should really be doing this? Might be better to let someone else do it who knows what they're doing
