electrical guru's need some help?? 22re
« on: Jan 15, 2007, 02:08:35 PM »
so here's my problem my truck has been down for 6+ months and i was getting ready to start and nothing... i cut the front clip off so i had to make some grounds up that i lost when i cut off all the sheet metal... maybe i need more grounds? i the main ground off the battery going to the frame and the ground on the fuse block grounded at same location...
the motor was grounded to the body but i grounded it out to the motor mount. <maybe thats my problem?>
the ground on the back of the motor goes to the body. i grounded the main power source on the drivers side to the frame rail as well...?

i had to extend the fuel pump connections and when i spliced in new wire i think it may have been a smaller gauge? would that cause my problem maybe not enough juice running through the wire?

also i moved my coil to were the wiper assemble goes and when i did this i had to extend two wires a black one and a black one with a red stripe. again i used smaller gauge wire could this be another problem? and there is a little thing ??? that bolts up were the coil mounts on the fender well... does this have to be grounded with the coil?

when i connected a battery and i thought it would fire over it clicked like the battery was dead, or it had a bad ground so i redid the grounds and now it won't even click like it is trying to turn over... i hooked up a head light and it work, the door buzzer works the dash works but maybe i don't have enough juice to turn the motor over and only enough to power small accessories??? :smack:

thanks for the help

also i checked all fuses and everything is hooked up right i went off of my other toyota to make sure everything was were it goes

Which side of the motor mount is it grounded to? It should probably be grounded to the frame or the frame side of the motor mount.  Also i had a car once that would only click but the lights and door buzzer worked but the battery was just too low to crank.

Take some jumper cables & ground the engine to the body & the engine to the frame. Any electrical that you had to relocate should be connected back up the way you took it aprt, this way there is no question about it.

so can using a smaller gauge wire effect that coil and fuel pump?? jumper cables is a great idea thanks..... does it matter were i ground the wire on the drivers side i think it is a main ground for the harness and it has a small inline box that is black plastic and has a stud inside of it with a ten mill i think nut.. and two wires on it?

Just so you know, the jumper cables are for testing only, not perminant. Keep the same size wire for everthing. Toyota didn't spend millions  :hammerhead:  in R&D for you to use a smaller wire especially with the coil & fuel pump. As far as grounds, make sure you have removed the paint & grim & it has a clean metal surface to contact  :thumbs:  You can paint over it after you get the truck running. Ground the cab to the engine, the cab to the frame, the engine to the frame & the battery to the frame.  :attention: Make sure you soldier & heat shrink all your connections. Don't use butt-connectors, you will have problems later if not now!  :smack:

Always use the same size wire or larger when extending. A smaller gauge will act as a resistor and cause voltage drop.

Also, how did you make the connection? Crimps or solder? Crimps will have a tendency to corroded and be a problem too. Solder and shrink tube is your best choice.

Can you describe in better detail what happens and does not happen when you try to start it?

ok i will go through today and redo all my wiring or were i have spliced in wires... i solder everything but connecters are junk and they currode like no other....

when i tried to start it, the headlights work the door buzzer works and the insturment cluster works all the small accessories work but nothing else when i go to turn it over i get nothing but a click and the volts drop to nothing so either the battery was not charged enough but i don't see how that would be because i had just pulled it out of my daily... so that leaves the grounds i have had problems simaler to this before and it was wire connections and grounds

i realize that the jumper cables are just for a test... all my cable are made from copper welding wire so they are beef and i should be good on grounds i have ground spots clean on the frame and body were i grounded the cables maybe i just need a couple more??

i have grounds from
battery to frame
motor to body
motor to frame
i will need to add a ground from battery to body and from body to frame
and about the little thing not sure what it is but i know it is bolted down with the coil and ignitor but i don't know if it matters were i ground it out maybe i need to move that to were i moved my coil?

thanks  :beer:

Your big ground wire from your battery should be bolted on to your engine block.  The starter is the one drawing the most amps so you want the ground to be as close as possible to the starter and the shortest path to ground which is the block.  There should also be misc. ground wires to your fusebox, body, and frame.  Hope that helps.
