Lead acid battery charger (or alternator) switching to trickle with (2025 Update)

Bugger, can't be that because no fuses should stop that unless the stupid frog car doesn’t fuse those windows.

Not spending money on stuff for one little purpose like that. And I can't see it would tell me anything, apart from "it happened at 5am".

What makes you think it's a door? It happens randomly overnight when nothing has been moved.

Do you say "bugger" with this accent?

But you did with the charger to kludge around the fault. And you should be able to flog it for about what you paid for it once it has fixed the problem.

When it happens and the detail of how it happens may well allow you to work out what is causing the flattening of the battery overnight and fix the problem.

It’s the most obvious way to pinch a cable.

But the change in the metal around the door may well happen as the ambient temperature changes overnight.

A 13.8V 15A power supply is very useful for all sorts.

Too much hassle and I lose postage and Ebay fees etc. Only time I've bothered "renting" something like that was a top of the range slide scanner for a large amount of 35mm slides I wanted digitised.

What can it tell me apart from the time of night it did it?

Actually I've just had an ABS wire fixed that had been damaged by the handbrake.

I won't know which door from the reading from the data logger.

Pretty close with the blokes. Nothing like the women and I never say bugger me with you bloody poms around.

How long that high current lasted for. That would definitively distinguish between the alarm being triggered and eventually timing out and a pinched wire which would have quite different timing, particular over different nights.

Sure, I didn’t say it’s the only one. And that one wouldn’t be fused either. Neither would the airbag triggers.

Yes you would from when you opened and closed a particular door. And you could do the other movable stuff like the bonnet, boot, hand brake etc too.

I know it's a long time as it can flatten the battery.

Airbags certainly are fused. I know people who have taken the fuse out.

Not with a that intermittent fault.

But you don’t know if its continuous when it happens or intermittent. If it was intermittent and regular it could well be the alarm triggering, then timing out, the triggering again and then timing out again etc.

You wouldn’t normally get that with a pinched wire.

Mine arent.

But you don’t know its fused in your steaming turd with wheels.

If you do see the 4A current, you will know that door or other thing like a handbrake did it if its only seen with that door and it would be trivial to only exercise that door etc once you first see that it happens with that door to get it to happen again even if it only does that intermittently.

True, but I'm not spending any more on the problem.

So if it shorts it just causes a fire? Everything should be fused.

More fool you when is peanuts and the alternative is to have to manually charge the damned thing every night.

They are internally fused. That way they cant set fire to the car and can't have the fuse pulled by a car thief.

Modern car security is about a lot more than not having a fuse for the alarm in the main fuse box.

I've already spent time and money trying to trace the f****ng fault and I've had enough of it. My current system works fine. I leave a pair of croc clips sat at the end of my drive and connect them every time I come home, not a hassle at all.

The fuse must be at the start of the circuit, or a short in the feed wire can cause a fire. Imagine a table lamp in your house with a fuse in its plug, but the cable leading from the consumer unit to the socket is unfused. What do you think would happen if a rat ate the wire in the wall? Now consider a car where shorts in wires throughout the chassis are much more likely.

What?

So you are actually stupid enough to waste far more time manually charging it every f****ng night. No surprise that you are completely unemployable.

Yep, you actually are that stupid.

Wrong, as always.

And yet you claim there is no fuse at all for the alarm system.

And we know that there isnt one for the starter etc.

That’s the situation with the starter in every car.

That’s what you claim is the situation with the alarm system.

Non key systems.

Takes f*ck all time. Whenever I come home, I pop the bonnet as I get out of the car then clip two croc clips to the battery as I walk round the car to the house door.

So why does your house have the fuses in the consumer unit and not halfway along the wire?

There will be a hidden one, so theives can't pull it out.

That would require a f****ng big fuse.

Which doesn't have wires running through the dash where it could set fire to the inside of the car. All the starter would do if it shorted would break the battery or the wire.

So have they finally removed those annoying alarms that wake people up in the middle of the night?

And my car has a key.

Takes much less time with the fault fixed.

Takes much less total time with the fault fixed.

With your stupid system, there is one in the incomer, one in the CU, one in the plug, one in the device itself.

What I said.

Which might just be why there isnt one.

But does have a wire running thru the engine compartment where the petrol is which is even more likely to set fire to the car.

Or set fire to the car.

Corse not, because thieves can still break windows etc.

Because it’s a steaming turd with wheels frog car.
