CB750 Alternator lead
« on: September 26, 2018, 03:55:51 PM »
I have just received a new lead from 4 into 1 purchased through Ebay.

Came through very quickly from US

Looks good and came out at £22 inc postage.

Alternator Wire Harness - 31110-300-154 - CB750 CB750K CB750F - 1969-1978

https://www.ebay.co.uk/itm/Alternator-Wire-Harness-31110-300-154-CB750-CB750K-CB750F-1969-1978/172403613700?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649


Was not sure if I would be hit with import charge but luckily not as I seem to recall there is a concession up to £15 ?

May be useful to anyone needing one .

I decided to go for a new repro loom from DS, so thought would be good to replace this bit as well.

I have also ordered the combined regulator rectifier from Amazon at c £15 to give a try.

I do have some old original units but at that price worth a try.

Should have had a word with Big Al on here. Uprated loom cabling and gave me free connectors that had melted on the loom it connects to. Ex British aerospace

Thanks Simon, I much prefer the dual (black & white) glass fibre insulation as fitted to the original CB750 alternator harness. Honda and Kawasaki (image attached) chose this specification due to the extreme heat/vibration around hot engine components.
Modern plastics & heat shrink insulation are good, but will dry out and crack when subjected to excessive heat/vibration.

Current bikes:-
Honda CB750 K4 (1974) USA
Honda XL500S (1980) UK
Honda CD175 sloper (1968) UK
Honda CB1100A (2013) UK
