That looks like four Lead Acid batteries in series, so 48v ?

Cant quite see where the wires are loose ?

It doesn't help that they seem to have used same coloured wire on some of the batteries for positive and negative connections.

Certainly looks like it could do with a little tidying up around the last batteries negative terminal and the plug area

Hard to tell, but it looks like you have 4 batteries in series and then shorted it all out by hooking the negative of the first battery to the positive of the last. Is your bike a 48V system? Do you not know how to hook batteries in series? Maybe this will help.

thanks jerry but any input u can give i see the positve is going to possitive and its just wrong 100%?

 

[smokesession]

so all negative to negative and all postive to postive?

 

[smokesession]

so TOP = Possitive Out neg pos neg pos neg pos Negative Out
Bottem SAme?

i only have 4 batterys not 8

Negative to positive for series.

A crash course might be helpful- note the batteries are always in a 'string', and series increases volts while parallel increases capacity.

Start on one end.

Connect + to + on that plug. On that cell, connect the - to the + of the next cell.

The next cell, connect the - to the + of the next cell in the row.

Keep doing that, till all you have left is a - that one goes to the - of the plug. I'd use a black wire for that last - to the plug, to help you not mix them up.

 

[jerrysimon]

Good advice.

I still don't get what that white wire is for ?

Jerry

 

[dogman dan]

IMO, the white wire is not needed. its a neutral or ground. IMO, should not connect to battery negative.

 

[jerrysimon]

Ah thanks, that makes sense.
