Okay, I must be stupid or something.


Thought my batteries were dead because I was gettin low cranking amps, batteries are fine; connections werent tight enough, as I slipped the connectors free of the terminals with my hands. Anyways I have now reconnected the batteries into my truck:

Positive on the drivers side into positive on the battery terminal, negative on that battery into the negative on the other battery, then connect the positive?

If so, thats what I did and its not working, help?

i must be stupid
 
Alright went a tried that and it took me 15 seconds to realise that i have no idea whats going on.


Passenger Side Drivers side


Starter Wire going down, some to master
| cylinder and clutch master or in
| that area,
| (positive) | (positive)
| Battery
| |
Battery | (negative)
| |
| (negative) |
-------------------------------------------------|


THIS IS ALL USELESS It wasnt when i typed it out though

Should I flip the right battery and wire it up?



Okay nice, I draw up a diagram that takes 5 minutes and it is hopeless

Okay well I went and had some icecream and a coke, and then I went and tried again, am I supposed to get a massive spark that melts the connection thingy and sprays molten metal?
 
Okay. well now I know that, "No.," I am not supposed to get a massive spark; could anyone tell me how to not get a massive spark?

I agree with Lowenbrau's advice to you but -- No! You definitely shouldn't get "sparks and molten metal".

Unfortunately I can't understand the relevance of "passenger's side" versus "driver's side" etc.

Is there someone knowledgable near you that you can approach for help perhaps?

Don't continue "blind" because you may inflict real damage.

:cheers:
 
Okay I wont continue, thanks, Yah there is someone to help me but i have to wait a few hours :P


Yeah the relevance of the drivers side, passenger side, isnt very relevant, but merely included to be used as a visionary tool when picturing the problem as a hole, for any people who are visual thinkers.


I have absolutely no clue what I'm doing; I'll leave it at that.
 
Yeah you bet, thanks for asking, and thanks for the help so far.



I lost my key for my truck, there is a few settings on the ignition:


START

ON

ACCS (I believe)

LOCK


I can only go through the first the settings with my popsicle stick key.
 
How about letting us know the model and location of the vehicle? It can help as some models have different battery configurations depending on where in the world they were sold to. Also, when you need to replace molten parts we can recommend Geoff Walsh vs Lordco vs Autozone.
 
Alright, well I drive a 1980 BJ40, 24 volt. I live in Canada and the truck is about 24 feet in an west south west direction relative to my current seating position in front of the computer. Its on the road and its windy and now raining.



Okay, well facing the truck from the front:


left battery positive goes to starter motor, and the negative is connected to the positive of the right battery, and the ground on the negative of the right battery.... However, this was how i believe that I had it when it sparked intensely moreover i switched the right battery around and connected up the ports without sparking and then i proceeded to attempt to draw a current and nothing happened.


i tested one battery with the volt meter earlier, not sure why i only did one, and i drew a voltage of 11.67.



Any idears?
 
dirty terminals, loose connection, a short - check your cables....

oh and yer that's 24v ;)
 
one battery on the low side will have 12 volts.


Forget thinking sides. Where the starter and the other wires connect(+) is the high side battery. Consider it battery #2. That's where your system is going to read 24 volts.

With all the wires disconnected and the ignition key off. And ensuring there is no power loads on, any where in the vehicle.

Put on some safety glasses, or you may truly end up blind.

Hook up the start wires and the rest of the ignition wires to the #2 battery positive connection. The negative connection must go to the positive of the first battery #1. Then the number one battery's negative connection will get grounded to the frame.

Alway hook up the ground last. Always disconnect the ground first. That's the rule.

If you melted to post too much you have to buy a new battery, which in a 24 volt dual battery set up means you have to buy two. They have to be replaced in pairs.

If you were to get some minimal sparks hooking up, it would only be when you connect the first battery(#1) aka lowside, 12 volter.... to the frame ground. As it would then make a circuit to the pos on the #2 battery.

Sparks mean something is drawing the current. But sometimes you get tiny sparks from stereos and door lights.
 
Perhaps you've jammed the ignition switch in the "start" position with your "popsicle-stick-key"?

(Honesty! If you're prepared to use a popsicle stick as an ignition key, you can't care much about damaging your BJ40!)

:D:D
 
Yeah I connected it that way, and didnt get any sparks,


I used a piece of metal usually to start it :P

And a nail head, and the popsicle stick.

My keys flew out of the ignition the first time i drove it and the keys went through a hole in the floor i guess, so thats what ive been using.

Its not on start, gauranteed.
