    Getting a bit desparate so have posted this on a number of sites to see if anyone can help:

    Fitted a 12v Alphaline XV31 battery as a temporary measure to replace the 2 x 6v workaholic batteries that were shot.

    The on board generator will not start. In fact there does not seem to be any power to it at all now. Before, with the duff batteries the generator was showing a fault to indicate that the house batteries were run down. Now there is nothing lighting up at all with the new battery fitted.

    Do I have to reset anything or could it be a fuse blown when I reconnected the new battery? Or could it be the battery itself going from 2 x 6v to 1 x 12v.

    Thanks in advance

    Check you rv petrol levels. Your on board genny will not start unless you have at the very least a quarter of a tank full.

    Check out the oil level in your genny, it will not start if the oil is very low.

    Have you checked with a meter or lamp that 12v is getting to the starter motor?

    thanks Jim,

    all levels are good. Normally the genny start button will flash when pressed but now nothing. No sound or any indication that anything is happening at all. The only thing that happened when I reconnected the battery that may be related was the A/C unit started bleeping:Eek!:

    Already done that Larry but no replies (Bingo_66). I wasn't able to use the same user name on here for some reason.

    I will separate the question from an existing thread and try again.

    Peter, not that mechanically minded unfortunately but if it's an easy job then I will look on the net for instructions and try that.

    Thanks for the info.

    Mmmmmm, a bleeping sound is usually associated with a low voltage. Me thinks that you have installed your new batteries incorrectly but I don't know how.

    Try putting your old but knackered battery back in the way it was before and try starting your genny again.

    I know it sounds daft but try it with your RV engine running. If the genny fires up, its the new batteries.

    All that you need is an amp/volt meter. You can get a meter from Halfords.

    Jim,

    Thanks for the info. I have actually installed a single 12v battery to replace the 2 x 6v batteries that were in originally (As a temporary measure) The old batteries were completely gone so have been discarded.

    The 12v battery is a deep cycle battery (Alphaline)

    any chance you have a bad earth?

    Disconnecting the batteries is it possible you have upset the earth? often genny issues are about earth issues. Especially at the genny itself, I often take the blt off the connection of both side and give them a good wire brush.. but check the area of the battery connection and see if by any chance you have a bad earth or a short.

    Lets be clear. What battery/batteries have you changed around. Your rv engine battery or your habitation battery/batteries.

    A deep cycle (leisure) battery is not good for starting anything as if you take a starting current from it you could buckle the relatively thin plates and completely knacker it. If you're starting an engine (e.g. genny) you need a starter type battery, i.e. ordinary car/van battery)

    The spec for the Alphaline battery of 115amp/hr with 1000cca
    should be perfectly adequate to start your generator.
    You need to check the battery is in fact charged.
    Then check the main battery connections especially the earth(negative).
    also check you have the positive lead to pos(+ Red) and negative lead
    to neg(-Blue) on battery.

    Regards
    Steve

    Thanks Steve,

    The Alphaline is a new battery and I put it on charge for the day before taking it to the RV. I took pictures of the 6v set up before disconnecting the old system and re connected the cables exactly to the new battery but left out the cable that connected the two 6v batteries together.

    The entry step and clock on the wall started working straight away and the A/C bleeped for 5 minutes or so when the new battery was connected. I tried starting the genny with the vehicle engine running but there is no power even going to the start button (It normally lights up when pressed)

    I am not sure if there is a fuse somewhere on the system that may have blown?

    Thanks for the kind offer. Unfortunately the interior is out of the vehicle for re trim so it cannot be moved. I think I may have to resort to calling the auto electrician.

    Thanks Cheyne.

    Have you left a small feed wire off?

    When you disconnected the wiring, any chance you left a small feed wire off the positive side?

    I know you say you left the bridge off that was used to connect the two 6v .. I take it there were two of those, one negative and one positive.. While I run two 12v on my Winnebago I still have a feed to other things and you have to be carful to make sure that they are all back and connected.
