Looking at my megafuse holder. Id think I need a jumper from the output side of the solenoid to the megafuse or another heavier(2g) wire from the battery.
We need a picture of what you're talking about.
The output side of the starter relay has nothing to do with the Mega Fuse. It runs to the starter and that's it.
My question, the mega fuse was a landing pad for switched B+ for headlights, A/C etc. I had originally planned on using a relay/fuse panel inside my tool box(pic). Now I'm thinking of just using an accessory 7 circuit Painless fuse panel which only requires a 10g wire to feed it. Seems there should be a smaller fuse for each accessory inside the tool box rather than a large amount of amps sitting there feeding each......correct? I'm probably thinking too much again. No, I might be right. Hell
I don't have any real idea what you're talking about. Pics?
An aux fuse panel, by definition, has individual fuses for the loads/accessories you're speaking of already. And yes they do need fuses.
And yes, 10ga wire is usually more than sufficient for most loads this aux fuse panel is going to see.
What's the Mega Fuse for? Just the alternator charging wire, correct? The Maxi-Fuse in your box is for the main accessories and standard fuse panel. If you want another fuse panel you could feed off of that and upgrade to a higher load fuse, or better yet give it it's own fuse so you don't risk overloading one 10ga wire if it's in distress.
To the comment about amps, none of the accessories sees larger amperage feeding to it than what it asks for. A heater motor is going to take, for example, 20a whether your alternator is a 20a unit or a 200a unit. And whether you use 20ga wire or 2/0 welding cable. If it only needs 20a to work, then that's all it gets.
Current is "pulled" through the wires, not "pushed" into the wires for everything.
if Painless gives you 4 constant B+ out of their fuse panel...what accessories would be wired to those? I don't have elec fans or fuel pump. What could I use them for? Leave them for later?
Yes, most likely.
What do you have that needs constant 12v that is not already handled? Headlights and brake lights? Should be handled. Hazards? Should be handled? Horn? Ditto.
If you can think of something that needs it but is not already included in the normal wiring, that's what they're for.
So yes, keep them for later unless you know what you need now.
You might end up using one of them for a small fuse panel for just small accessories such as interior LED lights or something.
Anything that you are NOT likely to leave on after you leave the vehicle and drain the battery.
I use mine for communications sometimes, because I don't usually need anything else running while in camp waiting for stragglers to show up on the radio. But not many need radios anymore.
Extra power ports over and above what you already have wired in when something else strikes you as necessary.
