Evening,
Both my boss and I have p38's, which we both leave parked up for 3 weeks at a time (for the last 3 years)....and both always start perfectly fine when we come back to them.
But last Thursday, i parked up at Gt Yarmouth port in our own designated car park....came to it early Monday morning to find a flat battery. Jumped a spare on it, to get me up n running. (Went for an 80mile drive, so i'm confident it had a decent charge by the time i got back)
Then my boss mentioned the following day that his had battled to start.... so we tried his last night to find that also flat. Checked mine today (Friday) and it's flat
My battery is about 3 months old.
Put a voltmeter on mine when i'd just got it started tonight using another battery, and it was at 13.8v (a little low i guess, but this was still charging up my flat bat), his was charging at 14.5 (but he did go out for a drive on Weds night, compared to me on Monday)... Checked my alt about 10mins later and it was putting out 56A.
So from this i'm confident there is nothing wrong with either charging system.
..... answers on a postcard please ?
I'm sure i've read somewhere on the internet about P38's sometimes getting interferance to the alarm receiver ? Does this ring any bells to anybody ?
Tonight it's parked up alongside the rig about 400yds from the car park, so i'll check tomorrow if she fires up ok ???
Cheers
Gordon
