Help with 5 amp fuse blowing

[fusa]

I finished wiring my panel, and checking all wires. The 5 amp fuse is blowing whenever I hit the power button. Any ideas what would cause this? The schematic I used is below.

The old, incorrect schematic was removed to not cause confusion. The correct one is here.

so without turning anything on, you just turn power on and the fuse blow? sounds like a short to me...

 

[fusa]

The fuse blows right after I turn the power on.

 

[icebob]

with all accessories switches to off?

 

[icebob]

are your pumps and rims connected?

 

[fusa]

yes, all set to off and nothing connected

 

[icebob]

if you have no load and you blow the fuse, it's wiring, do you have a multimeter?

 

[fusa]

yes, I have a multimeter

 

[icebob]

this is what I would do, disconnect wires at pin 9 of the PID and power up and see if fuse blow ( you may want to go to autozone and buy a couple packs of fuses!)

 

[fusa]

disconnected wire connected to 9 on pid and the fuse blew

 

[icebob]

ok leave pin 9 disconnect, and disconnect pin 6 and 8 at the timer ( if you want to save some fuses, remove the fuse and connect your multimeter with the red lead in the 10 amps plug and the end of the lead to one side of the fuse and the black lead to the other side so we can just read how many amps you're dragging)

 

[fusa]

Did you mean pins 6 and 9 at the timer?

 

[icebob]

yes sorry!

 

[icebob]

if you have lots of fuse, skip the meter part....

 

[fusa]

disconnected wires 6 and 9 of timer and pump switches work, that did something

I just bought 3 packs of fuses

 

[icebob]

fuse didn't blow?

 

[fusa]

yes, it didn't blow

 

[icebob]

reconnect 6 and 9 and disconnect 1, 2 and 4 at the timer

 

[fusa]

I also tried connecting the PID 9 wire back, the fuse did not blow when it was tested

 

[icebob]

that's good leave it connected, now we know pid is good

 

[fusa]

disconnected 1,2, and 4 of the timer, reconnected the 6 and 9 of the timer, turned power on and the fuse blew

 

[icebob]

look like you have a bad timer, lemme check your drawing again...

 

[icebob]

Leave 1, 2 and 4 disconnect and disconnect pin 8 at the timer...

 

[icebob]

looking at your timer internal right now....

 

[fusa]

Left pin 1,2, and 4 disconnected and disconnected pin 8, fuse blew again

 

[icebob]

reconnect 8 and disconnect 9

 

[fusa]

reconnected 8 and disconnected 9, the fuse blew

 

[icebob]

let me think a little...

 

[icebob]

problem is at the 8 line, the internal of your timer don't match your schematic tho, but let's try something, ( hope you're not in a hurry, electrical problem can be time consuming!)

I have today, Monday and Tuesday off work, plenty of time, and thanks for helping me.
