Rewired hid's and lightbar and got a quote on the back 225/75/14 tires today. Also wound up the torsion bars again and put the air shocks up to 120 psi for towing. Got new wireing part way done. Rewired dash and key. I now have an acc wire. 720 is not running at the moment. Got spark fuel everything. Just no starter motor.

I have to say, get all these little bugs worked out and you'll have one bad ass little truck.

And I agree with everyone else. Consolidate all your problems to one thread and make your life (and the people who are trying to help) a bit easier.

 

Yeah. :) im starting to think the same. :)

update. tracked the fuel problems late today. the click in the motor was a BOSCH 0580254044 installed by the po above the tank on the left hand side. since being ripped out and replaced with a stocker shes running super smooth at 650 rpm idle got the new alt in not long ago (4:34am now) 14.4v idle with 60 amps at 3k on the tach its at 123 amps. just ordered a ton of parts to get it all sorted. it goes to the workshop on the 21-23 to have the new motor rebuilt (again -_-) getting the carb rebuilt at the same time and having the clutch done(cant get to the clutch without pulling the motor currently) selling an ac bracket to a fellow ratsun member in the coming weeks. (your us prices are insane) replaced the "T connector" as it was connected to a cut wire in the cab (hence why the alt never worked well)

ive just gotten some new parts to finish off the wiring. 

 

list is as follows.

2 narva 54435 fuse blocks

30 meters of 6mm red cable

30 meters of 6mm black cable 

30 lugs to suit

2 100amp relay as currently everything is hooked directly the battery is draining 24/7

10 40amp relays 

100 m3,m4,m5,m6,m7,m8,m9,m10 bolts washers and spring washers and nylock nuts (kit)

professional carpet is being installed before its finished off at the work shop

200m of 2.5mm cable (black)

200m of 2.5mm cable (red)

3000 peace electrical connection kit

30pcs hss drill bit set

new seat covers

6 stage battery charger (will be permanently installed)

velcro zip ties. (got sick of using 100 packs in weeks)

1 dual usb outlet (2x 2.1amp) to replace the lighter socket

drill chuck (thanks to me not thinking the fan ate the last one. 

2m aux extension

2m usb extension 

another jigsaw.
new drill.
just got a 200pcs tool kit. makes things so much easier

got a 4m x 2m sheet of plywood for a box to house my speakers (behind the rear seats) and replace the kick panels that have rotted away over time.
got second hand door cards
replaced brake pads 
exedy clutch kit
new spark plugs
used cluster (mine failed finely)
 
total cost of 
AU $1131.24

the motor was only done a few weeks ago so by law its covered in full for any and all work required to fix it. 

 

 

registration is on the 8th of october and it will be about 500$ so for that 2 weeks i doubt much will happen.
