Battery Connected Backwards
Hi All,
I installed a new battery in my '88 Wrangler but connected the wires backwards. Needless to say there were sparks, hissing and smoke coming from either the bottom of the battery or below the battery. The car starts and runs but the radio does not work and the volt meter shows just less than the first mark (I assume is 10V). Can the Jeep run on the battery if the alternator is dead and how long will a new battery last like this (I still need to drive home -15 miles). Can anyone advise what damage has been done and what needs to be changed? And yes I know it could have been much worse and was a dangerous mistake to make...stuff happens. Thanks in advance for any advice. Steve |
Re: Battery Connected Backwards
You have blown the fuse link for the alternator by the sounds of it.
These are located on the relay just below and to the right of the battery on the firewall. Follow the positive cable to the relay post. The fuse links are bolted to this same post. You can buy new fuse link wire at some auto shops or even the dealership to replace it. They sell it by the foot. It is fairly expensive. You will need a 'red' one or a 14 ga. one. The fuse link wire is about 8" long with a loop on one end and a fat black tube crimp connector where it connects to the harness wire. The blown one will be a 14 gauge one protecting the 10 ga. alternator cable. You need to match the length and use crimp connectors. You cannot solder fuse link wire without harming it.

Re: Battery Connected Backwards
Steven,
Yes, you can run on battery power alone until the battery gives out. The length of time depends on the amount of juice you draw off the battery and its reserve capacity. Do not turn on any unnecessary electrical device such as the stereo, heater, or headlights. At best you may have a couple hours. To replace the alternator with a rebuilt/new one will run $100/$200. The problem may be........ what else was damaged? The battery itself may be damaged as the alternator tried to charge it the wrong way, fusible links may have burnt, fuses/circuit breakers fried, and if your Wrangler has a computer it may be hurting also. One good sign is that it starts and runs.... Once you get home put it on a charger and try out all the electrical stuff, lights, turn signals, etc. Be sure to have it charging...... modern batteries do not take kindly to being fully discharged and prefer long and slow charges. good luck... <tempjeep@rodda.com> wrote in message news:1143218909.532593.289440@t31g2000cwb.googlegr oups.com... > Hi All, > > I installed a new battery in my '88 Wrangler but connected the wires > backwards.

Re: Battery Connected Backwards
Do you think he's fried his radio? The good news, is that you can buy a
really decent radio now for $150 or so, compared to what was available in 1988.

Hi Steve,
There's no way you can reverse polarity even for an instants without popping the alternator diodes.

Folks figure out it's the wrong way before they can get it tightened down usually but it's the last touch that blows things. The positive post is bigger so if you are hooking one up correctly, negative last, then you can tighten the positive clamp down on the negative post, waaay down mind you to grab on the negative. They should have done it the other way around because the negative clamp won't fit easy on the positive post, it has to stretch open way too much. The aftermarket ones fit both usually though....

The positive post is bigger so if you are hooking one up correctly, negative last, then you can tighten the positive clamp down on the negative post, waaay down mind you to grab on the negative. They should have done it the other way around because the negative clamp won't fit easy on the positive post, it has to stretch open way too much. The aftermarket ones fit both usually though....

Re: Battery Connected Backwards
Hi Doug,
Yes, most dry cell batteries will not make a connection reversed in any other than a flash light which of course wouldn't be critical like a portable radio.

Re: Battery Connected Backwards
Yes but then the $tealership wouldn't get the big bucks to replace the
fuse links and con the marks into the 'fact' their alternator is blown too.... He is lucky the ignition wasn't on. The ignition module will normally cook before that link goes.
