Repair The Traction Inverter Module
This may not be your problem but , I can tell you another Ranger EV owner sent me his TIM and it just happened I had one that had been setting for the last year since I did not have an idea what was causing the problem ... the 7.5 amp fuse in the fusebox kept blowing out with the one I had and the one that was sent to me was intermittently blowing the same fuse, this actually made it so I could test it before the fuse blew out which on mine would not give me that chance but it made it so I could track down the chip and find a replacement chip for both of them !!
here is some quick pics of what I found and the replacement chip I used that fixed the problem.
the other error code you will get in the TIM diagnostics is a contactor circuit failure and the ranger ev will not start ........................
Of course I followed the manual to remove the TIM so as not to be bored here is the TIM when I first opened the Lid...................  of course everything on the left side had to be taken out of the box just to get to the main board which is of course where the problem is at ............
Finally I got down to the culprit , this is the bottom board in the TIM that needs the work ....
OK a little closer you can see the IC chip right in the middle standing upright is the IC chip I found that was the problem ................................
Here is a close-up of the IC chip , I had a hard time at first as most IC chips have the numbers on the bottom 1/2 of the chip and very plain to see... for some reason this company put it bold and very hard to read and I had never heard of a chip starting with BUK until now ..........
but I found it thankfully through the internet interchange guides and finally came up with a NTE crossover # .............................
Well I even got extremely lucky and came up with a local electronics store with 2 of these hanging on the wall !!  installed one in each TIM and finished putting them back together and both of them came to life with no errors .. I put them in my Ranger ev and went for a test drive of over 8 miles with each one ... boxed up one and sent it back to its owner to get him back on the road .....................................
 
  And so now I have had another learning experience , I really never had planned on getting into these since they seemed to be quite strong but since there was 2 of them with the problem I am guessing this may be a weak link in the module and hopefully this is the only problem they will run into !!
 
  Since the Last time I checked these were almost $4,000 exchange , which is a hefty amount out of pocket if they are bad .........................................  hopefully this will keep a few guys from giving up on their ranger ev ..............................................
