Notts_TT Posted April 3, 2013 Share Posted April 3, 2013 Hi Supra has been parked away for the winter and I went in a few weeks back and there wasn't enough juice in battery to start it..... I left it a a few more weeks and now has no power in battery at all... A mate came over in his golf running 6 batteries and a 230amp alternator and we tried to jump it with some leads, that wouldn't work, not even a light on the dash would light up, it did nothing... Surely if it was a battery problem the jump off the golf would of done it ? Please help..... Thanks Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted April 3, 2013 Share Posted April 3, 2013 Just put a new battery on it, jumping aint a good idea really Quote Link to comment Share on other sites More sharing options...
listy Posted April 3, 2013 Share Posted April 3, 2013 Sounds like the battery has gone into deep discharge. In other words, the battery is totally dead and you need a new one I reckon. Quote Link to comment Share on other sites More sharing options...
Notts_TT Posted April 3, 2013 Author Share Posted April 3, 2013 Wouldn't jumping it with leads even power car up a tad ?? Quote Link to comment Share on other sites More sharing options...

l.chris97 Posted April 3, 2013 Share Posted April 3, 2013 could you not disconnect the battery and hook the golf up to the terminals and just check if the dash lights come on to prove the point, but at that stage it could be easier just changing the battery.

Kaan W Posted April 3, 2013 Share Posted April 3, 2013 I cant see how it wouldnt start as its just the same as using another battery sat in another car with longer leads thats charging at the same time Quote Link to comment Share on other sites More sharing options...

Josh42 Posted April 3, 2013 Share Posted April 3, 2013 HB005 or HCB005 pal. If you know anyone with a trade card you can get one for £46...if not around £90... Quote Link to comment Share on other sites More sharing options...
listy Posted April 3, 2013 Share Posted April 3, 2013 I cant see how it wouldnt start as its just the same as using another battery sat in another car with longer leads thats charging at the same time If the battery is completely dead, ie no charge left what so ever, then the battery internals won't conduct a current. Therefore, the circuit has a break in it, and will not work. Quote Link to comment Share on other sites More sharing options...

So taking the battery out the equation, and plugging the jump leads straight onto the battery leads of the car as if you have a fully charged battery just the only difference being it not sitting in the car? I dont get how this cant work. Quote Link to comment Share on other sites More sharing options...

Dave Posted April 3, 2013 Share Posted April 3, 2013 if the batterys dead even the space shuttle wouldnt jump it,you need a new one mate Quote Link to comment Share on other sites More sharing options...
Kaan W Posted April 3, 2013 Share Posted April 3, 2013 thats what i was trying to say in my post above..can't see why that won't work Even if the battery was still connected its the exact same as having 2 batterys in parallel but with one dead and the other fully charged it will by pass the dead battery at the terminals in my logic. Or removing the battery and using someone elses is the same as having a battery in the boot but with an alternater charging it. Electrics are not my strong point lol....

But he should still get an interior lamp to illuminate from this method? Which failing to get any kind of voltage into the car means some kind of main power fuse has blown?

kjgreen3 Posted April 3, 2013 Share Posted April 3, 2013 Should have worked off his mates car especially with a 230amp alternator (medium revs at least 2000-3000rpm) and heavy gauge 600ampish jump leads. Only time it may not is if the battery is ok and deeply disharged and sucking all the current from the jump to charge itself. It the battery is fubared it wouldn't interfere with a jump start. My guess is check the main 120 amp fuse. If that has popped putting a brand new battery in will not start the car or light the guages.

Notts_TT Posted April 3, 2013 Author Share Posted April 3, 2013 Where's the main 120a fuse ? I was thinking same as kaan w... Surely it would just draw current from the other battery and alt... Is this this fuse checkable.....? Quote Link to comment Share on other sites More sharing options...

Dnk Posted April 3, 2013 Share Posted April 3, 2013 (edited) If its blown it'll be melted at its narrowest part which is visible through the clear plastic top Where the blue arrow is Edited April 3, 2013 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Kaan W Posted April 3, 2013 Share Posted April 3, 2013 Can u tell if it's blown ? Yeah because there will be no power Honestly without looking what type of fuse it is I have no idea, just look for the obvious, blackened edges, broken filament etc. Quote Link to comment Share on other sites More sharing options...
Dnk Posted April 3, 2013 Share Posted April 3, 2013 If it is blown you have to unbolt this fuse from underneath, its not a push in fuse Quote Link to comment Share on other sites More sharing options...
Kaan W Posted April 3, 2013 Share Posted April 3, 2013 Just to add there is 3 nuts to remove the fuseboard from the casing 2 of which you can see and the other is hidden under the red + cap, before you go trying to force it out Quote Link to comment Share on other sites More sharing options...
