honda xr125 again

[barker]

I ve got a 03 xr after a lot of head scratching it runs turned out to be a duff plug mind you it was new anyway now its going ive noticed its not charging, now I know the regulators on later Hondas are prone to early failure but as there rather expansive I wont to be sure as to what it is will test the yellow wires out of the alternator , as I understand it if I put my multy metre on two yellow wires on dc it will give me 18 volts , if ive got this right is there any other common problems to check

Hi your figures look a little high on continuity and low on the charging, according to manual 17-5 0n, you should be getting 14-15v at battery with engine at 5000rpm, would check out alternator , coil and reg/rec again

sat and had a cup of tea got togged up and went for a spin on my t80, during this 40 mile a hour ride it went around and around in my head its charging at the stator its working at the regulator why is it not getting to the battery ..then it hit me it had to between the regulator and the battery

rushed home now with a idea in my head, disconnected the connecter from the regulator to the battery there it was staring me in the face the pin was greener than my lawn as I tried to clean the pin the wire fell off so after cleaning things up the wire was soldered back on the pin , put the pin in to the block joined the two halves to gether fired her up put the nullity metre on the battery 14 .5 volts

made another cup of tea and drank it with a silly contented grin as the bike sat there ticking over

Hi matey always the wiring, glad its sorted

[barker]

thank you spanner for your input

trouble seems to be you have a idea in your head as to the problem what you sometimes need to do is stand back and approach it from a different angle as in my case

hope the other xr gets sorted in Scotland as easerly
