Hi all. Not very good at this as usual you only come on these forums when you need help. So please be patient and any help/advise would be appreciated. The problem: My 96 Disco aover heated after the water pump pully seperated from the shaft ( a new replacement of less that an hours use), This has now been replaced. The problem is that every time I turn the ignition key to start the engine the main 100amp (alternator) fuse blows. Any advice? clean helpfull one would be appreciated. Thanks

Was any wiring disturbed when the water pump was fitted?
Hi Sniff
Yes removed and cleaned each one in turn and replaced. Please keep the questions coming even if u think its obvious, these are good memory joggers, in case I missed somethig..
Is there anything else that uses the same fuse that might be causing it to blow, ie the heat sensors

Replace the fuse but leave the alternator wires disconnected then run up and see if it blows. if it dosent then you know you have a short in the alternator
see #6
Hi guys to both question: Thanks for response: First tihing I checked was the battery connections. I am currently out of fuses and will have to get some tomorrow, and try again. Have disconnected the alternator ready for when I get new fuses.
#6- is there any thing elase that is powered by the same fuse?

nothing that should blow a 100A fuse except, possibly, the starter motor
remove main power cable from startermotor.
MAKE SURE IT IS WELL INSULATED BEFORE TURNING POWER ON!
oh - and disconnect battery first. To be honest, I dont think the starter motor is fused.

hi Folks not been on for sometime. I would like to thank all of you for all your advice, howerver thie situation has gone from bad to worst, not having much success with the "white elephant" the saga continues.........removed the alternator and took it to be checked out...OK.. checked all the wiring and reconnected, replaced the fuse and it started no fuse blown..... smoke started to come from the alarm? so disconnected it..assume i replaced the wires (3 all together ) incorrectly..any ideas???. anyone has a photo on where they should go, they can post for me thanks.
Hi it was a cry for help as tit was woring no problems until i took thr wirung apart to check.....i thought i had put them back in the right positions but not sure now...hence my request for a photo of the connections to to the main fuse box under the bonnet so as to check the positioning. Im in kings lynn norfolk. Ric
