An expensive non-test drive...

[Kristian]

Hi guys,

Hotwire (Lee) came round to my place yesterday to test drive one of the Legnums sitting in my driveway, and with a flat battery, the one I was using for test drives needed a jump start.

I was chatting away to Lee and his lovely wife while I was doing it and so I failed at Jump Starting 101 - hooked up positive to negative and presumably have now blown the fusable link, rooted the alternator etc etc.

I know a few of you guys have had this happen to your cars coming in from Japan - what did you need to do to fix it? Luckily I have another Legnum I can pilfer parts from temporarily.

Cheers
Kristian

Jeez Kris.. you really droped the ball mate! Any chance it's just the alternator? Surley a rebuild wouldnt cost the earth. Although, getting it out might be the pricy part.

hmm I'm guessing it doesn't start at all now? Does it try and turn over with another battery? What about lights and stuff on the dash?

 

[Kristian]

Nah starts up fine, so the computer's all in tact, but dies as soon as I remove the jumper leads.

 

[Hotwire]

It started with another charged battery connected, but once removed car died So was not charging itself AT ALL

EDIT: Kristian beat me to it

damn! lucky my test drive went alot smoother then! lol.

you've probabilly just killed the battery,
the car wont run with a dead battery...
you may have caused it to colaspe a few cells or all together...

they wont run if the voltage goes below 10.5v ish.

even if the alt is fine, and the battery is stuffed, it wont keep going.

put in a known working one to test it with,

once started use a multi meter acrcross the + and -,

should be about 13.5v ish

ive done the backwards battery in mine,
replaced a few fuses, my main 120 or is it 110? amp fuse went,
replaced it and all was fine.

SLY-031 (Joel) Paid $665 for his alternator recon - Ouch!

This is his breakdown of the cost...

$320 labour (charged 4 hours instead of 5-6)
$345 for alt recon.

thats from Blackwood Dyno tune.

Good luck mate...

i done that once, it collapsed a cell in the battery, thus not allowing it to hold any charge...i'd replace the battery first, and if that don't work, check the main fuse, as all current should pass through that first ( unless cranking...i think)....hope that helps...
