Newbie here so be gentle.
I recently bought a 1999 curvy which had been sat for a little while.
The bike went straight to a mechanic who got it road worthy and through its MOT however it’s got an issue with the electrics which the mechanic never looked at (the bill was already running pretty high) and now I’d like to get it sorted but need some advice.
The issue was first noticed when the lights were on and the bike was rev’d. The lights dimed a little and then came back. I’ve also noticed that when the indicators are on, the dash lights dim as the indicator comes on and off and that’s with lights on and off – not sure if that’s usual.
I’ve checked the voltage across the battery terminals at various set ups and to me it looks as if the battery isn’t being charged when the lights are on. I’ve searched through loads of threads about similar issues and tried a number of the recommendations but I’m still having the issue.
The voltage readings across the battery are all as below and I’ve checked the regulator rectifier abut this gives normal diode readings – I’ve even swapped it for another and there is no change.
The battery is about 4-5 years old but has been on a trickle charge for most of that and seems to run fine.
Battery was fully charged using a trickle charge and then tested 36 hours later. Reading was 12.7V
Lights off:
At idle: 13.4V
2.5k rpm: 13.5V
5k rpm: 13.5V
All seems ok, just.
Lights on:
At Idle: 13.1V
2.5k rpm: 12.6V
5k rpm: 12.6V
I’ve been using the bike without lights and never had a problem, however when I ran the lights for a little while the other day (about 8-10 miles), the bike struggled to tick over the following morning and I only just got it running.
I’ve gone through as many of the connectors as I can around the right hand rear fairing and cleaned them up / added some WD40 and cant see any obvious issues with the cabling anywhere on the bike.
Any advice / recommendations on what else it might be and how to go about fixing it?
