Originally posted this question in the engine forum, but it was suggested to try it here.

?
Are you just putting it togeather to drive or what? If you want the absolute correct place wait for number dummy to chime in

 

lol, yes just to drive, rather than show. But I still am kind of **** about things. I would move it if I needed to, but if I can keep it in the stock location, all the better. Also, I want
it to be properly grounded, so the stock location will surely be good. I think I may have seen it strapped to the firewall , but not positive.

I respect Numberdummy and all his parts knowledge, but I'm not sure if this is in his wheelhouse.

Thanks for your input.

 

l am not **** on the stock locations but, l am always looking to ground properly for better electrical proformance. I had a few ground straps from the aircraft world l used on my as well as welding cables. I solder all my connections and have a battery anti corrosion gell l try to put on my connections. Maybe l am **** l just didnt realize it.

 

No pun intended right! ha!

The stock wiring and grounding locations are kind of a weak area on these old trucks. Manufacturers used the shortest and smallest diameter wire and cable they thought they could get away with, depending on the steel body and frame to complete the ground path. When everything is new and bright it sort of works, barely. Fast forward 50 years or so and all the corrosion and rust causes problems. The path your truck took for the negative ground might have been from the battery to firewall, and then firewall to engine block and on to the starter and ignition. A better setup will run a heavy gauge cable direct to the block or bolt on the starter. It pays to be particular about grounds and connections. Better starting in both cold and hot weather, and better charging, and hotter ignition.

 

On my '62 uni the ground is connected to the rear of the drivers side head and to one of the gas pedal bolts. The cable is about 6 inches long.
Good luck

 

Thanks to all who responded. It seems that I should probably upgrade the system a bit better than stock. I'll probably start with the usual grounding points and add some additional at points that will help to make the whole system stronger 💪🏼💪🏼
