unplugged zip drive while it was on. fuse blown?

I got a mpc3000 a little while ago with a zip drive off ebay. when i first got it i tried to plug it all in and get the zip drive working not having found out you weren't supposed to unplug it while it was on. I don't know if the zip drive was formatted and i don't know how to format it. long story short it has sat there after i tried to get it to work and couldn't figure it out. I tried the configuration that has been said: termination on id set to 5 and connected to the zip side of the drive and it didn't work. did i blow a fuse? how would i know? I opened it up and didn't see any blown looking resistors. Is it the zip that blows or a resistor in the mpc? who would i take it to to figure out how to fix it? since its been sitting i also had a flood and it got wet a little. i was exhausted from moving stuff around and it sat for a couple of days until i could figure out how to open it up and try to clean it out scrubbing it with a toothbrush. i found a little moisture in my lcd display and some rust on the solder of the resistors. It was supposed to be a 3.11. i am planning on sending it to rohan to get upgraded with vailixi 3.5 if it still works. sincerely noob

The fuse that blows when an external SCSI device is used improperly on an MPC is inside the MPC.

The fuse is labeled F901 on the SCSI/ D IN Board. You would need a multimeter to measure it to see if it is blown. It is not obvious by looking at it.

Changing it will require soldering.

If you are not skilled to do this, you will better off taking it to a repair shop as you may damage the unit further if you do not know what you are doing. Most electronics repair centers would be able to change this for you. The service manual is available in these forums you can print that and take it with you to the repair shop.

thanks. i've got a multimeter and i'll check it out and see if i can figure out how to use it.

As a general rule, don't just pull the plug on your gear, turn it off first.

The power button is there for a reason.

Just to add on:
When connected Always,
Power On SCSI Device first then MPC

Turn Off MPC first then SCSI Device

even if you have a blown scsi fuse your 3000 will work fine with a zip drive. my scsi fuse has been blown for almost ten years. i use a cf reader and zip regularly.

^ I think that depends on if the external device powers the chain..

for certain devices you need active termination with a blown fuse. but with a zip drive you dont need anything but the zip drive.
