Afternoon all, I have a Beta 43 with what I believe to be a 95 Amp domestic alternator and a Beta controller. A few days ago, I started the engine to allow it to warm through while I de-moored and there was an occasional faint warning bleep and the domestic light on the panel was flickering. Once I unplugged the shoreline, all went back to normal no light flickering, no beeping so off we go with the intention to investigate later. As we were cruising, the faint beeping and flickering light re-appeared occasionally. With nowhere to pull over we continued and I assumed that It was the alternator failing and would need replacing. Once moored up, I investigated to find that the engine loom was burnt out on a couple of wires on the domestic side right back to the panel, the damage being so bad that I have just had to replace the full engine loom right back to the panel! I was not able to 100% establish the cause, presuming that the loom had chaffed against something below the fuel filter as this appeared to be the source. (The new loom does not have the facility to connect to the heater plug relay, Beta say this is fine as we only have a 3 meter harness from the panel and all appears to be fine) Since replacing the loom, all is fine, no warnings and both alternators are charging, however, when I start the engine with the shoreline plugged in (to provide us with hot water) The domestic alternator light is flashing in a consistent manner along with the warning beep. This never happened before the incident with the loom. I have spoken with Beat but they are not able to offer an explanation. Has anyone come across this before? Any thoughts? Is it possible that the damaged loom has damaged something in the domestic alternator? Hopping that all of this makes some kind of sense! TIA Keith.
Here we go again, one problem fixed now another!!! Can anyone help with this alternator query. I had a new Beta 38 fitted in March 2013 which has 2 alternators, one for the starter and the other or the domestic batteries. Until yesterday I've had no problems with it (although when it was fitted I was told my wiring is a bit odd). I went to start the engine and the warning buzzer continued to beep even after the engine was running. Also the domestic battery charge lamp was out. Then I noticed the smell of burning plastic and on opening the boards was greeted with a cloud of acrid smoke. After turning the engine and batteries off and letting the smoke clear I found the green/yellow (earth?) wire from the alternator had melted off most of the insulation and the wire was exposed and snapped in places. I tried to replace the earth cable and turned the batteries on only to hear more cracking and smoke issuing from the repaired wire. I've now disconnected the Domestic Charge Sub Loom (95 Amp) and fortunately because of my odd wiring the smaller alternator is charging both my starter and domestic batteries although it seems at a slower rate and not as deep. I fear the worse that the alternator has died but as a minimum the Domestic Charge Sub Loom (95 Amp) will need replacing - am I missing anything obvious do you think? I'm very much an electrical novice, so please use idiot proof terms for me
