Electrical issue

[nickgolf101]

Ok, so I pulled the fuse block and determined that the block has some corrosion in it. I ordered a new block (what a pain in the butt to find one that has 18 slots!!) and it should be in next week... I think this will solve all my issues!!

I couldn't find a decent fuse block with 18 circuits either, that is why I went with two blocks. I liked the easy labeling, the cover and there is also an equal amount of negative terminals on each fuse block... The two blocks were just as easy to install as the one.

My 2800 came with two blocks. I replaced mine as well.

How would you connect 2 fuse block?

You would just need to split out the main 12V that feeds the 2 blocks. The seperated fuse circuits don't care if they are in 1 or more blocks.

I just used and 8awg jumper to feed the second fuse block (pos and neg).

You gotta be careful on this one. You'll need to keep a few calculations in your head:

1) Max Amperage rating of the fuse bus.

2) Max Amperage capacity of the Positive and Ground wires to the block.

In this scenario, you are drawing the entire amp draw of the fus bus through the 8g line. For example an 8AWG has a theoretical limit of 55amps.

12awg = 20 amps
10awg = 30 amps
08awg = 55 amps

You'd need to add up the total number of circuits and their anticipated draw. Also keep in mind, if you 'daisy-chaining' from one fuse bus to the next, then the total sum of both fuse buses is being drawn through the circuit to the first fuse bus in the circuit. The leg from fuse bus 1 to fuse bus 2 might be sized properly for fuse bus 2, but the circuit to fuse bus one might not be sufficient to carry to the entire load. Capacity planning is where 'DIY' gets people into trouble.

Just something to consider.

Ended up replacing 18 circut with two blocks, a 6 circut and a 12 circut... All electrical is working now!!! Thanks!

Glad to hear now enjoy the season.

Shrew- the second fuse block wouldn't be in series(daisy chained) with the first block. Think of it like this: what is the difference if you have one fuse block or two fuse blocks... As long as you are using the same amount of circuits with the same fused amperage ratings? It is the EXACT same thing, you are pulling the EXACT same amount of current throught the main feed wire. The 8 gauge jumper is acting exactly the same as the pos BUS does in a single block.

good thread. thanks for the information as I posted a similar topic the other day.

I don't believe I'm disagreeing with you here.
