350 not charging the battery
Posted: 05 May 2024 19:05
Hi folks,
My name is Layton and I'm based in Darwen lancs.
I'm a newbie to the site and in fact any site lol!
I bought my first Morini about a month ago. A 1982 350 k2 Italian imported about 2000. It was a non runner with the alternator removed. The vendor believed it wasn't charging. The elderly chap he'd bought it from had given up on it.
I found a receipt stating it had been rewound about 8 years ago by NLM. It looks newly wound with no heat damage. The bike doesn't seem to have been ridden in all this intervening time.
The NLM ignition was goosed so a SACHSE ignition kit, coils and regulator fitted . Sourced from Doug at Mdina, a top fellow who has been a brilliant help.
I've got it running after several attempts to fix the original components. And it sounds bob on.
Unfortunately it's not charging the battery.
There's 30+ volt coming from the 2 yellow leads when measured to earth. 1.5 yellow to yellow.
There's 20+ volts from the red lead measured to earth. The multimeter shows charge when in series to the + battery terminal but connecting directly to the battery there's no evidence of it charging the battery, just the batteries 12.8ish volts. I'm worried about putting high voltage through the harness and cooking the ecu.
120+ volts from the now isolated green.
White goes to earth.
None of the regulators I've fitted have provided a charging current.
I am really at a loss. I've been bodging bikes for getting on for 50 years but this one has got me beat.
Does anyone have a suggestion, or highlight a peculiarity of these machines that could point me in the right direction?
Thanks in advance for any help - Layton
