Konsort Duo Battery Charging

[Keith Bousfield]

I have owned Konsort Duo KD14 for a few months and recently noticed the Auxilliary Battery indicator light flashing red when the engine was running. PANIC! People tell me this is a common fault and I should ignore it. I have spoken to Martyn Morris and seen his posts on this forum and read other notes about the system but feel I have a different problem and would welcome any advice. Since noticing the fault I have checked battery voltages and the situation is typically as follows:
Before Starting: Engine Battery 12.7v Auxilliary 12.4v
Engine Running: Engine Battery 14.4v(green) Auxilliary 11.8v or less (yellow or red) This is seen regardless of the load that may or may not be put on the battery (Instruments, lights etc.)
On stopping, the engine battery voltage gradually falls to 12.7 and the auxilliary rises to about 12.2v and shows red and green!
The voltages were measured across the battery terminals but the same voltages can be measured at the Split Charge Relay.

I have had no problem with auxilliary battery life during my few months of ownership before I noticed this, and none so far since. I have changed the auxilliary battery and am fairly sure it is not the cause of the problem.
Do I have a problem with the Split Charge Relay?
Any advice is welcome. Keith Bousfield - Watershed

I would suggest that you phone Brian Kinder of KDD PowerCentre (http://www.kddpowercentre.com/page31.html) on Monday morning. His company supplied most (if not all) the electrical systems on the Duo's, and he is the best person to advise you.

He came aboard my boat, and noticed a fault on the switch panel that I had never even noticed!

Let him know that you are a WOA member.

Dear Philip,
Thank you for your very quick response. I followed your link, sent an email to Brian, and had a reply. All in less than 24 hours on a weekend!
He thinks I do have a problem with the Split Charge Relay. I will look at it again and if necessary return it to him.
I will let you know the outcome for your information, but for the moment many thanks for your help,
Regards
Keith

All fixed! - Many thanks to Philip and to Brian Kinder of kddpowersytems who thought immediately it could be the Split Charge Relay, suggested a test method and, when confirmed, supplied a replacement in a week. Very impressive!
