Traction control light

Hi guys,

Long story but today i came into work to find one of the trucks had a flat battery.

So i went and got out my jump leads and hooked them up to the truck and my dual battery in the back of my 110.

The battery was pretty flat so i started reving the engine in my defender in neutral to create extra power. All of a sudden my t/c light started flashing on and off. As soon as i took the jump leads off it stopped and i cant get it to do it again. Is something wrong or what could it be?

Only happen with the jumper leads on....

Maybe the leads were slipping.

Sorry I couldn't resist ha ha ha

Haha..

I called my local mechanical centre and they reckon that it should not happen and ive got an issue

$$$$$$$$$$$$$$$ Cha Ching. You have major problems book it in with us and we will fix it. Ha ha ha

Unless it happens while your driving or happens again more frequent, I wouldn't worry.
It could have something to do with a surge of power or could not, maybe just a coincidence, or a glitch. Wait it out or go test the TC in some slippery stuff.

Interested to know how you go about that.One of our CAT 12Ms has an electrical issue,if the operator hasnt isolated it we have to get the 24V isuzu service truck to jump start it.

Andrew I actually think I read somewhere that the new 2018 Defender is going to be 24 volt so it can be used successfully to jump start real trucks without causing fault lights to come on. ... :angel:

I sorted it out today with our auto elec.
The way he set my dual battery means that i shouldnt be jump starting anything in the first place. Its set up to run all my auxilry things...
I blew one of the fuses and caused the computer to go spastic. New fuse and circuit breaker and all sorted ;)

Did your auto electrician explain the difference between 12 volt Defenders and 24 volt trucks?

[DazzaTD5]

There seems to be an assumption that the truck is 24V

Depending on if its a U.S, European or a Japanese truck, it could be either.

Yes I am assuming that it is 24v, because nothing has been said by the op to say it wasn't since this point was first raised.

If it wasn't then fair enough.

Sounds like you put the full 24V thru the 12V system,very lucky to have only fried a fuse and circuit breaker.Cant see why you shouldnt be jump starting anything from it in the first place,its a 12V battery,a jump start is no different from any other 12V load on the system.
With the CAT grader you cant get to the batteries without spanners,there is a 24V jumper point so havent tried the 12V start.We have started trucks/loaders etc 12V to 24V but you need to know what you are doing.

haha yes good point, as in the OP would be jumping up stating it was 12V, instead as you have pointed out, we hear silence.

*So ooops its 24V hence blowing fuse.
*Even if 12V the amp load of jumping starting a truck blew the fuse anyway.

On side note, I find fitting a "jump plug" onto the front of a Defender a good addition...

*No more trying to get jumper leads under passenger seat.
*high amp cable connected direct to primary battery.
*high amp anderson plug on front of vehicle.
*fit off a good quality set of surge protected jump leads with an anderson plug
*high amp battery isolator switch inside vehicle, so anderson plug is only live when needed.

Every customers Defender i've fitted this to admits its awesome once they have used it! And of course a jump plug is only needed on a Defender to start other vehicles right?.....:p :p

My son has an Anderson plug off his starter battery under the bonnet and it is very useful. For example, when camping recently we were able to plug the folding solar panels straight in to it and the power flowed from the starting battery through the battery controller to the second battery, which was running his fridge. I have an Anderson plug off my second battery for connecting the solar panels for direct charging.

Just on that, when my starting battery died, I realized I might be able to jump start the vehicle off the second battery which is mounted in the back of the drawers in the rear, accessed by lifting up the seat. So I hooked up the high amp jumper leads between the batteries and away she went. Not recommended off a deep cycle AGM I know, but it worked. An advantage of having two batteries.
