Had a minute when I stopped by the shop and snapped a couple of pictures. This is the CLC open top electrician's bag that I keep all my basic service tools in.
Middle section holds Fluke 87V, set of Snap-on mini picks (in a Gearwrench pouch), M12 3/8" ratchet, and Snap-on 3/8" QR flex ratchet,
and most important of all; hearing protection!
1/4" flex ratchet, 1/4" GW sockets on a rail, SK spinner handle, MAC 3/8" locking extensions (for spark plugs), spark plug sockets, tape, Hex and Torx keys (in reality I only need maybe 4 sizes for valve adjustments and lugs, but then they'd be easier to lose). Usually there's a battery terminal puller behind the keys, but not sure where it walked off to. Also has a small parts box built into the bottom with fuses, batteries, crimp connectors, heat shrink, small hardware, etc.
Feeler gauges, Snap-on spark plug gapper, Snap-on 3/8" mini roto ratchet (for spark plugs, again), mini screwdrivers for adjusting VR pots, xacto knives for scraping gaskets, colored tape for IDing leads when loadbanking, some misc sockets in the small pocket.
Couple of screwdrivers, 3 nut drivers, small prybar, oil filter pliers, pliers wrench, dykes, Knipex hose pliers and Channellock E318 needlenose for pulling fuel and block heater hoses.
10mm Williams combo and ratcheting wrenches, angle and offset box wrenches for valve adjustments, fuse pullers for BBS5 fuses in transfer switches, long punch for lining up holes, extendable magnet, razor knife, post cleaner.
CLC bag for actual repairs. Just toss in what i need per job. I don't keep anything in the pockets
As you can see, the problem this time of year with the open top is getting rain and snow slopped on and tools rusting. I could ditch a good amount of what I'm hauling around if I wasn't doing as much smaller home standby stuff.
