If it ain't broke dont'y mess with it
« on: June 01, 2025, 05:58:13 PM »
Took the bike out for a quick tour round the block this morning and decided to check the charge voltage before venturing out since I had had the regulator off the bike.  11.68V  :(

Been struggling with a dying battery and still not sure if the battery is at fault, it shouldn't be given its age but the evidence is stacking up against it. Thought I would check voltages anyway before setting off.

I fitted a spare regulator and everything seemed to be as it should be.

Having a look inside the duff voltage regulator, there was a bit of paper towel between the N/C contacts.  I decided to clean the contacts when I had the regulator off the bike when doing a batch of zinc plating and included the resistor cover  because it was looking a bit scabby.   While off the bike I thought it was a good idea to have a look at the contacts and give them a wipe with some 2500 grit paper. After that I soaked some paper towel in WD40 and pulled that through just to make sure there was no grit remaining. Looks like a bit of towel got left in there. After removing the towel debris , 0.2Ohm across the contacts instead of 120.

Lessons learned:-

- If it aint broke dont't b****r about with it
- get some better glasses
- test refurbed electrical items before refitting

If I mess with anything electrical I either get a shock  :o or make things worse.  ::)
