Hi help required I accidentally swapped polarity in my is200 i tried to start it and it blew the 120A fuse and starter relay then the hazzard warning lights stayed on constant untill i realized and swapped the battery back. Now the car will turn over but wont start have i fried the ecu? Any ideas would be appreciated.

 

Did you replace the 120 amp fuse? Check all fuses every single one.

 

Not yet i just replaced the relay and main fuse do you think there are more blown.

 

any update on this?

 

I need to replace the 120A alternator fuse in my IS200 SE AUTO Mk1 but can't find any reliable information showing the correct procedure to properly gain access to the fuse & relay block.
I know which box the fuse is in, but it apparently has clips somewhere that need releasing so I can get to the bolts?

Has anybody done this successfully before without drilling or cutting through the housing? Did you find any videos / pictures or diagrams showing how to release the clips that I can refer to?

I've got the workshop manual PDF but it's a nightmare to navigate (have read hundreds of pages so far but not found the appropriate diagrams, so will keep plugging away at that unless anybody on here can point me in the right direction?)

Many thanks in advance,
Paul.

 

It will be similar to this. Ignore the video title it's supposed to be 120 amp not volt
