All you need to do is replace the battery and while you're at it replace the battery wires. If you want a molded (highly recommended) terminal you'll need to look through the selection at an auto parts house to find one with the right length and configuration (1 or two wires).
It's a relatively simple job provided that you have everything before you start... running around for the little pieces can drive you nuts.
Buy a new battery to start off with then you will have to either change the battery cables to sidepost type mounts or buy sidepost type mounts and install them on your old cables.
With the two batteries side by side connect a jumper wire from the positive post on one battery to the negative post on the other. The remaining neg and pos posts on each battery will supply the 24V your looking for.
It is underneath the backseat on the driver's side! Remove the positive and negative wire from battery post...pull battery out and replace!!
On the same post connected to the battery.
make sure the key is in the off position, remove battery post don't let the red on touch anything this is a hot wire. Remove the battery, ( if you have a post holding the battery inplace lossen bolts move handle and remove battery, replace battery the same way. DON'T LET THE RED POST HIT ANYTHING THIS IS A HOT POST YOU WILL BLOW SOMETHING UP.
you have to have 2 wires. then you put a wire to the positive side of the battery(+) and the other wire to the negative side of the battery(-). then both other ends to the light bulb one end to the side and one end to the bottom. you have to have 2 wires. then you put a wire to the positive side of the battery(+) and the other wire to the negative side of the battery(-). then both other ends to the light bulb one end to the side and one end to the bottom.
Should be located on inner fender usually passenger side. Battery + to one large post Starter wire to other large post Small trigger wire to (either if 2) small terminal
battery cable and all fusible link wires go on the side of starter solenoid that is marked ( B ) , and yellow wire and starter wire go on the side that is marked with an ( S ) , Ignition switch is the one that plugs in on the top of the solenoid that is marked with an ( I ) Other than that there is a ground wire that grounds separately to the side wall that is separate from the whole solenoid. older models seemed to be very basic. some of them, had all wires on the battery side/ ( EXCEPT ) for the starter wire ( which by the way is the small red wire that runs next to the battery wire of which the battery wire is the big red wire and the starter wire is the small one. Always make sure that the battery wire goes to ( B )side and the starter wire goes to the ( S ) side. Because ,,,,, if they are put on in the reverse order of this, then you will have reversed the polarity and it will start, but will also fry the starter. If anyone else has anything further to add to this, or sees anything whatsoever wrong with this post, then feel free to add it . have to change part of answer. I posted the yellow wire as being on side with starter wire on ( S ) side of solenoid... Correction:: The yellow goes on the same side as all the fusible link wires and goes on the ( B ) side. The only wire that will be on the ( S ) side,, will be the starter wire ( which is the smaller of the 2 red wires ) plain and simply put also, the ( B ) on the ( B ) side of starter solenoid, stands for ( Battery and the ( S ) on the ( S ) side of the starter solenoid stands for ( Starter ) and the upper wire that is marked with ( I ) stands for Ignition ( ( which goes to the key switch )) the lower post of the Solenoid is not usually used on this model. But it is for the ( Coil ) if it is applicable, and it is not in this case , because would '''normally'''' be electronic ignition on newer vehicles.
The red battery wire goes on the positive + battery terminal no matter which side it is on. The black wire goes on the negative - terminal.
Mostly you will see it bolted to the engine.
1. open trunk2. remove floor boards ( 2 layers)3. you will see the battery on right side near the spare wheel4. loosen ground wire clamp (black wire) and remove it first from battery post5. disconnect red wire6. replace battery, secure it and connect RED wire first7. connect black wire
wire direct from + side battery to + side coil and jump starter solenoid
