Truck stalls after battery replacement (1 Viewer)

[augustine]

Hi everyone, new to this forum.

Recently I picked up an fj60 needing a bit of TLC everything worked great for about 3 months until the battery was swapped now it dies unless given gas on startup. Radio/features also do not work anymore. Originally I thought it was because the connectors were corroded so I switched them but am still having the same problem.

Never seen scotch locks on an unfused hot wire. Hope you're carrying a fire extinguisher.

I'd say that at this point your best bet is to grab a wiring diagram and new fusible link (still available from Toyota for the FJ60) and rewire the hot side of the battery.

you're missing your fusible links at the battery. Those blue splice / tap style connectors are terrible.

I didn't see the white wire that comes off the back of the alternator and goes to the fusible link at the positve battery post. More pics of your alternator to battery connection would help.

I see several cracked wires in the photos you've posted. Do you have a multi-meter to check for continuity? I would bet on a broken wire somewhere. Perhaps removing the battery was the last straw. Impossible to diagnose without testing though.

I'm guessing the red wire going to the positive post is for some aftermarket radio or other aftermarket equipment. The blue connectors are splice connectors...they work by shoving a blade into the existing wire and the new wire. The current runs through the blade inside the blue plastic. Maybe has it's place but not in a running moving vehicle. Disconnect this wire for now until you can get it running right. Later you can replace the wire with a solid wire going from battery all the way to whatever it's powering.

The white wire coming off the back of the alt should be hot( 12v) all the time. It voltage runs from the positive through the fusible link to the white wire. it runs thru the conduit up to the positive on the battery post. It should ideally run through a short piece of fusible link (looks like thick wire) about 4 inches between two plugs. Actually there are 3 fusible link wire and looks like this:

Test the white wire at the back of alt for current. At the fusible link plug...both sides.

circled in red at the top of image is an electrical plug that is not stock. What is this going to? circled in the lower part of the pic on both sides...the sketchy blue connectors.

Here is another tap/splice connector on a white wire. Is this the alternator wire?

Unfortunately you have what we refer to as a s*** show. Your best bet would be to pull the battery out and set it aside. Replace the battery cables and terminals. Get a new fusible link. Remove all the suspicious cob job add on wires but try to figure out what they are powering first. Redo your grounds while you are at it. Good time to invest in a digital multimeter….even a cheap one will work fine.

@ToyotaMatt can help you find a lot of the pieces you need.

Funny stuff......but he is not wrong OP. If that were mine I would start over. Your Cruiser deserves it. Would likely be way faster than trying to figure out all the hack - n - tap you got going on there. Here is a nice cable set to start with if the OEM stuff doesn't work for you:

FJ60/FJ62 Heavy Duty Battery Cable Sets

The kit costs $155.00 shipped (within US). International shipping is available. The kit includes 5 cables and battery terminal connectors. This kit fits FJ60's and FJ62's. See below for additional kits (FJ40, FJ80 and FZJ80) Kit includes: Battery positive to starter cable (with protective...

I hope you find the guy who did all that to that poor truck. GL.
