hi i have a 97 jeep cherokee sport 2 door the other day i broke down at a light. before it broke down i realized that the volt meter in thr=e dash surged. iv replaced the altenator and ingnition coil it still didnt fire it was missing spark so i looked in the fuse box first good idea i had and fuse 10 - the auto shut down fuse was blown i replaced it with the 25 amp yellow fuse that came out and it blow as soon as i turned the key i then replaced it with 30 amp then fuse 18 blew another 25 auto shut down fuse, i replaced that with a 30 amp and it ran fine but now it has a draw in the system that ate my optima red top battery what did i do wrong and how can i fix this

First thing you did wrong is putting a bigger fuse in. Never go over required amps. Now you need to run through and see what wires you fried or see if there is a related relay that might be shorting out and blowing fuses

I think wires are good I bought a new relay today I think that might be the issue..... And im converting to the original ampfuses

Lol that's a very good idea. Let me know if that's not it and i will try to dig something up. I had a issue with the tps sensor ended up being the clock spring so you never know

Yea I did the new relay and its not poping fuses anymore so thats good but idk if there is a draw or my voltage meter is messed up cause when it first starts itll read 12 then u drive about 10 minutes and its reading 9 but wen it did that the volt meter I attached to the battery still said it was at 12 so lol I didnt wanna trust it this morning on my way to work but ill take it out tonight and see wats wrong lol if it gets weak again ill know somthings messed up

I found out theres some reason the altenator is not charhing the battery all the fuses are good but a metyer says the altenator is sending any thing to the battery

If the alternater was not working properlly the battery would always be dead and if you jump it it would dies after like 2 miles if that.

It was a wire to the computer that controls the regulator or its regulated by the PC thats wat I found
