so its rrreally cold and my battery started not being able to take it, and i had to give it a boost everytime, so i went and bought a new battery, i installed it with a brand new ground wire, but i didn't have a new positve clamp, so i modified the stock one to fit the bigger post, (it was making pretty solid contact) then when i went to start it, the battery sparked and now i have no power whatso ever, no interior light, no lights on the cluster, no heater motor, no spark, no clicking, no nothing, so i took the battery and and charged it and tested it to make sure it was good, and it is, then i tested every fuse under the hood and under the dash, all are good, and all have power on both sides, i am stuck and can't find anything out. anyone have any ideas?

 

You sure you have good contact on your new ground?

 

yeah, 100% sure, i even took it off again and double checked, and i re-did the positive post clamp just to be sure everything was good

 

I agree with SOHCD16y8

It must be a ground problem if the fuses have power on both ends.

When testing the main fuses with the meter where did you place the neg.(-) probe of the meter?

If it was on the batt. neg.(-) post, move it to the cars chassis, [shock tower stud works well].

No power at all, to anything, means either a power or ground issue, [assuming batt. is good].

You say "the battery sparked", where exactly did you see the spark at? 94

 

yeah i was testing with it on the neg battery post, im gonna go try it somewhere else now, but from my sitting in the car view it looked like the positive post sparked

 

uuhhhhh.... what do you mean the new bigger post? ALL top post batteries have the same size terminals.....the only difference in the terminals is the negative is smaller than the positive.....soooo, are you sure you purchased a group size 52R, and not just a group size 52? you didnt list the Y/M/M so Im not sure which battery your car calls for....If you installed those battery terminals backwards, you're gonna have some serious issues.

 

I thought about that but he did say he had to modify the "positve clamp" for a bigger terminal, not a smaller terminal.
Lets all hope the batt. is not connected backwards.

TheAverageBear... If you say a spark at the pos.(+) batt. clamp when you went to start the car, it is a pos.(+) batt. clamp issue, either the clamp to the batt. post or the batt. cable to the batt. clamp.

Test for power at the main fuses with some kind of load on, [head lights], there can be continuity when there is very little load but no continuity as soon as the load goes up. 94
