No power at all

I’ve just installed a new alternator, before starting the install I removed earth strap off the battery, I installed alternator and went to put earth back on battery and it sparked the the positive side had some smoke,
Now I have no power at all.. I’ve been through all fuses and found a 10amp from under dash blown so I replaced it. It was for eng cont
It’s a td42 converted using all Tb42e wiring, there is one wire that goes to the battery that controls everything power wise but I don’t know where to look for fuse or relay that’s directly to that wire.. if anyone can help me shed some light on what happened that would be great! I’m going a little bonkers 😅

I think there are a couple of man fuse blocks in the small enclosed fuse box under the bonnet - on drivers side - next to guard - you need to unscrew the op panel to access - they look like relays boxes from memory. By some chance you didn't hook up the pos and neg battery cables in reverse on the alternator? Sounds like a main fusable link also? Can't recall where that is though.

nah mate I only removed negative from battery and I don't believe I did as far as alternator I just copied how it was already installed but I will have a look over incase I have mucked something up, also I have looked at those relays but everything looks fine? I'm not really sure what to do from here...

OK< there re also some big fuses in there as well, brown ones, green ones and white I seem to recall. One of those actually drops off all power to the vehicle - I think @AB might even remove his on occasion as an anti theft deterrent? I know the car wont run if its blown, or at least thats what happened on my GQ 2.8 once when I shorted out a cable. If the blue topped relays are damaged they would probably have signs of melting on the top covers, but sounds like they are ok.

yep I've checked them also and all is fine I'm really confused on whats happening... do the tb42e have a body control system? maybe I've burnt that out? I'm just so confused on how it even happened when all I did was remove neg cable from neg battery post swap alternators then put neg strap back to neg post...

Nope, I am out on this one now, sorry.

The fusible links are near the positive battery post. They have plastic connectors on each end.

checked all them too mate all A OK, I'm so stumped..

This is the main power , where’s the fuse or relay for this?

In mine there under a cover just to the right of your hand and just below where you have your hand , because it's been converted it's all different .
But if when you touched the leads the dreaded smoke came out something's amiss with the way you hooked the alternator up or possibly something was left on .

How did you get on? I have today swapped out my alternator and smoke tested to destruction an earth lead - still looking for root cause, however truck started first time, then nothing the next. I traced it to the motor glow plug fues that is in a bank of 5 units to the rear of the start battery - its the brown unit on the 'inner end' of the fuse cluster, rated at 7.5amps. Had a few spares as I am prone to doing stupid shit so all good, running well. Hope this helps

I sorted it all out. the wire I'm holding in the picture is indeed a fusible link and was the problem, also the new alternator has a little black insulator on B+ post and when removing from box it come off, so I had basically wired a short circuit , hence why the usable link packed it in, so after finding that and fixing the problem there I sorted out the fuible link by rewiring some 4b&s I had laying around , my problem with alternator however wasn't indeed a stuffed alternator, my car is a converted td42 from tb42e and the signal and warning wires that plug into the back of alternator were around the wrong way.. so alternator couldn't send current to battery , lucky its sorted because I was starting to go bonkers lol
