No but my dad did once on a bulldozer. Didn't help.

Curious if you ever pulled the "build a fire under it" trick to get it
started in the super cold?

If I have a large diesel out in the back lot on a day when the temps are
hitting 0 degrees, I need all the cranking I can get. Alternators
frequently go up to 16 volts. I will have some cable voltage drop. And
you do want to spin the motor faster than normal when cold cranking a
cranky diesel. Especially if you have run some thing out of fuel on a job
site. I have had to crank a backhoe a half hour to get it to go, and that
is after cracking open all the injector lines.
I remember back on the farm, our old 6 volt John Deere wheel tractor got
much more well behaved when we put an 8 volt battery in it and adjusted
the generator to charge at 9 volts.
Say you want to deliver 300 amps to a bulldozer
0 gauge wire has 10 milli ohm for 100 loop feet.
Times 300 amps leaves us with 3 volt drop.
So my 18 volt battery pack is now 15 volts. Should spin the engine
nicely.
I will probably do 16 volts. Like to know how much voltage those booster
starters put out. The only way they can give you more amps is to give you
more volts. I’ll bet they hit 16 if not 18 volts when in the boost
position.

Why the extra voltage? Compensate for resistance of long cable? Might be
safer to just spend more money for heavier gauge wire.
Having once exploded a battery I was jumping on a zero degree day, I am
cautious about creating sparks around hydrogen. Getting sprayed with
sulfuric acid is not fun. I guess if you follow the last connection to
the chassis rule you are OK. But the idea of using an 18 volt battery
would scare me. And is it really necessary?
If there’s AC available, I like the approach of hooking up a battery
charger. Let it charge for 10 minutes on highest current setting and most
cars will start even with a weak battery. But you are looking for a
portable system. Most of my portable generators have a 12V DC output that
they say you can use for starting cars or charging batteries. I haven’t
tried it. Need the special cable.

If there are any electronics in the vehicle, I would worry about it.

Yep, red for electrical. Black for mechanical. Like to have one for
plumbing and pneumatic I think. I have several Kennedy’s for
machine shop. On a different subject, finally got a newish forklift
battery. Old one had a bad cell that I had jumpered. Problem was you
couldn’t leave it on the charger without risking overcharge. Also
the forklift thought it was always low on charge and would shutdown
prematurely. Gonna build a boss man jumper battery system. Put it
in the back of the service truck with 50’ of welding cables. The
question is: how much voltage? 16 volts at least but I am
considering 18 volts. Enough cells to make two of these. One I
think I will make forkball with the skid steer for jump starting
around the shop. I know auto systems can take 16 volts without
issue. Is 18 too much?

Yeah, pretty nice chests. I bought one for the shop this year. I
also thought it was pretty cool that they now sell them in
like ten different colors.

For the past year I have been monitoring pricing on used
tool chests. Snap-On, MAC etc. Pricing them out by cents
per cubic inch etc.
Last week was in Harbor Freight getting some air fittings
and checked out their tool chests. Brand new price is lower
than the used pricing on name brand boxes.
So I bought a couple of them. One for mechanic tools one
for electrical tools and supplies.
Pretty nice. The castors are not ball bearing but at least,
for now, they are rolling nice. The steel is not any
thinner than name brand boxes. The ball bearing drawer
slides are better than some old non bearing kennedy and
craftsman boxes I have.
Too bad their sales always seem to exclude tool chests.
