1991 Swift Challenger, so getting on a bit. Away this weekend and the battery went flat while on hookup, found the anti surge 1A fuse in the KT12 had blown and kept blowing when we replaced it. All 240V circiuts working fine. Bought a battery charger in Halfords today and hooked it up off the mains and battery and all 12V circuits also working fine now. Also charges fine off the car. Its just this fuse in the KT12 so it won't top up the battery when on hookup.
Is the unit Kaput or is there a common fault to look for? The charger I bought today is an automatic one so I guess if the worst comes to the worst we can hard wire this in to replace the KT12? I know it wont act as a power supply as well but it will keep the battery topped up?
I presume the KT12 doesn't operate when charging off the car? The voltage needle certainly shot up when connecting to the car with the switch on car not van electrics so I presume this bit still works. Just that we spend a lot of time on CL sites off hookup so charging on the move from the car is a must.
If this is the case I'll get the smart charger hard wired in, Not a big job I guess.
Plug in Systems who made the KT12 normally use the middle position of the car/van switch for charging the van battery from the car.
Also in this position and while on hook up, for using the KT12 without a battery
The 'Car' setting is for running the van from the car battery, used with care this is handy if your van battery is flat.
OK thanks, so just to clarify we no longer have battery charge when on the move with the car. I'll have to find another solution then, like a secondhand KT12 or a more modern variant. What a shame.
Seems weird though as after the battery went flat at the weekend and we hooked it up to the car for 10 minutes on car setting, the charge went right up in the van battery (from dead to just into green?). Our switch has a car picture on the left, a centre position (no voltage reading on the dial) and van on the right.
At least we have a smart charger to keep the battery in good nick during the winter though.
Not sure what your saying, you should still have van battery charge on the move.
If it's a full 'plug in systems' system, I presume it charges the van battery in the centre position, that's not to say it's different to this?
To make sure, you need to hook the car up with engine running and check the vans battery is getting around 14v from the cars alternator
