Red face e450 2002 7.3 bluebird,battery drain in 10 secs

hi guys,im new to this forum and just got vehicle ,i did some research but couldnt find a solution
i cut off all the ignition interlock circuit breakers at both rear doors,there were 6 of them,then i cut off assuming power cable(10mm diameter or so,i traced it was hooked to secondary battery straight) for wheelchair lift(which is taken off too)and there also were 2 cables white and black thin ones,white was connected to circ.breaker and had extension to another 4 of them then extended further to *big block with tons of fuses,wires etc*
black one connected at wheelchair motor circuit breaker.
also both black and white cable came all the way underneath of steering wheel into fuse box and they splitted from there(2 white,2 black)which i couldnt where it lead.
i will attach pics soon.
sorry for mess in punctuation,etc. i aint native english speaker.
PS. Forgot to say,vehicle started first time after i used another *full* battery ,but after cutting some wires gauge just went down in like 10 secs from normal to 0,im assuming some short somewhere? or bad alternator diode ?

Pics attached ,thx

Just found out ,battery doesn't really drain it's just gauge ,coz I tried to start same battery in other truck and both fired up .So I'm assuming I did mistake somewhere,or circuit breakers still preventing ?

Both batteries should be tied together. Not just one to the wheelchair lift. And the starters on these things are pretty wimpy. A new starter cranks things over really fast. Luckily they are cheap + easy to change. Not saying thats what you need, but if the batteries are charged and HOLDING their charge, its next to do.

Lol,this forum is almost dead as many others
Idk,i traced and cut off all the unnecessary? wires,replaced bat and it starts somehow
now theres left over 6 cords to power tail lights and it wont work,im not sure what did i wrong,is there any relays i cant go further theyr taped in big bun in that box so i have to disconnect everything in order to figure out.
also does anyone know wheres speed governor for this vehicle,i could go only 65 or so.meanwhile f super duty 97 powerstroke doing 85 with 4.88 rear end and ~18-20k weight.i cant believe 10-13k empty bus cant go faster.
Did some research but no results at all.

i cut off all the ignition interlock circuit breakers at both rear doors,there were 6 of them,

They were breakers, like breakers in an electrical panel? I am not familiar with an ignition interlock, could you describe it's function, and/or post a picture?

then i cut off assuming power cable(it was hooked to secondary battery straight) for wheelchair lift(which is taken off too)

Are you saying you cut the feed cable attached to the panel with the breakers in it? Where is this secondary battery located?

and there also were 2 cables white and black thin ones,white was connected to circ.breaker and had extension to another 4 of them then extended further to *big block with tons of fuses,wires etc* black one connected at wheelchair motor circuit breaker.

These two white and black wires were fed along with the feed cable to the panel? The white cable was pigtailed to 4 other breakers, which then fed into a fuse block? All of this is taking place at the rear door, correct?


also both black and white cable came all the way underneath of steering wheel into fuse box and they splitted from there(2 white,2 black)which i couldnt where it lead.

Those two black and white wires then fed to the front of the bus, under the steering wheel and were landed in a fuse box, right? From there, 4 wires, 2 black and 2 white fed to an unknown location?


PS. Forgot to say,vehicle started first time after i used another *full* battery ,but after cutting some wires gauge just went down in like 10 secs from normal to 0,im assuming some short somewhere? or bad alternator diode ?

Immediately after cutting all of this, would the bus start?

i was able to remove all the extra cables,now vehicle looks stock,except i ignition switch wont crank starter,in pre-start turn it lights up,pumping fuel but wont crank,i traced voltage with my friend and it doesnt feed 12v when u tryin to start,fender solenoid was replaced,starter replaced,i can start it thru straight battery to small red wire on starter and it run good.but no ignition from key start.i think i just make push-button start from that.
other issue is tail lights,have trouble to finding original chassis tail lights wiring but found trailer one's and assuming i just run them.
third issue is speed limiter is set to 65 or so.i called local guy and read online looks like i can just reflash computer and can run 75 especially considering that i replaced tires also to 235/85/16 fromd 225/75/16
PS. theres some vampire drain if i leave battery connected(when all bus **** was in it,it would drain in less than a night,now in stock it still drains but much slower.).what it couldbe ?
