Electrics/Leisure battery help.

Post by Corden » Mon Sep 13, 2021 9:16 pm

Hello everyone.

I have just bought my first ever camper. A 97 Ford Freda. I need some help with the electrics and leisure battery. If anyone could help point me in the right direction I would be so grateful. I have no idea what I’m doing.

Firstly the van fires up and drives ok. I do however get a yellow coil symbol flash on the lower left of the dash. What does this mean?
I am not able to get any of the electrics working while driving, like radio and cigarette lighter. I assume these are rigged up to the leisure battery.
So the leisure battery might be completely dead but I can’t get any of the electrics working without hook up. The electrics work when using hookup. I have not had the fridge working though. Not even sure how to turn that on.

I have matched up and replaced any fuses I could see around the batteries under the bonnet. This didn’t seem to cure anything. Although I’m not sure if this has stopped the coil light on the dash. I’ve not checked that since changing fuses.

I have a power management system installed in the back of the van. This shows the level of the car battery is good and the van battery level is non existent. The hookup doesn’t seem to charge the battery either. Just makes a bit of a whirring noise? I think I should try and replace the leisure battery?

So if I should try a new battery, what kind of battery should I get? I don’t really know what to look for a part from the dimensions. (So it fits into the bonnet)

I’m sorry if this is a lot to unpick or if it’s a bit of a minefield, but I’m willing to give things a try and learn.

Many thanks.
NIcholas.

First the flashing coil lamp means that the ECU is flagging an error, just what the error is needs to be read out from the diagnostic connector down on the lefthand side of the passenger footwell. Details on how to do this are in the Factsheets in the members area.

It sounds quite likely that the leisure battery is flat, possibly dead if its been left a while. Use a voltmeter to check the state of the battery and then replace as needed.

If you need a new LB then as you say size is important, the trays are not standard in size or mounting height, then when you know the dimensions choose a battery that fits and has the largest AmpHour capacity - normally in the range 80-120AMpHours - a good source is https://www.tayna.co.uk/leisure-batteries/ make sure you choose the correct terminal layout most batteries come in either style.

Thank you so much for your reply. I appreciate your time. I think I've found a battery on that link that's very similar in size to one that currently installed.

I can't seem the find the factsheet. I've had a look in the members area and just seems like a list of members? Am I blind or am I in the wrong place?

Its the Bongo Fury Club members, possibly your looking at forum membership;
Click "Join Bongo" at the top of the page above,
then click "Sign in" if your already a member otherwise you'll need to join the club itself,
fill in your details and login,
finally click "Members Area",
you may need to scroll down a bit, then click FACTSHEETS and you will see a couple of sheets under Diagnostics to read.
