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.

 

[icebob]

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!)

 

[fusa]

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

 

[icebob]

follow pin 8 on your schemati and disconnect ant pin 11 of the switch just on the right of the 5A fuse...

 

[fusa]

disconnected the pin "11" and the fuse blew

 

[icebob]

btw here's the manual for your timer...

 

[icebob]

can you confirm your timer is a jsl-71A not a jsl-71?

 

[fusa]

DAMN!
used wrong schematic, this was the updated one

 

[icebob]

yep power need to come from pin 10...

 

[icebob]

rewire accordingly and let me know, I'm afraid about your timer...

 

[fusa]

Connected everything the way it should have been connected in the schematic above. Everything seems to work.

I had saved all version of the schematic that I had, assumed the newest one was the up-to-date one. I was wrong.

Thanks for you help!

 

[icebob]

happy ending that all that matter!

I'm trying to figure out the diagram you posted in your thread starter (first post) There is something basically wrong with that diagram as the wire plan for the Auberin Timer JSL-71A is different than shown in the drawing. The terminal blocks appear to be flipped. Check it out. terminal #'s 10 & 5 should be on top. I cannot find a copy of the drawing you posted in my files. Could you please let me know the source you used so I can trace it back and fix the problem.

Please...

Edit & Note: After a lot of research I figured out the problem with the first diagram posted (and since deleted). The original was a diagram develeped for a very early version of the JSL-71 Easy Timer. The wiring plan for it was the one displayed in the original diagram (very old early version).

Here is the manual for that timer version: http://auberins.com/images/Manual/JSL-71.pdf

By the way that version is no longer available. The current products use the diagrams setup displayed in the posts now available in this thread.

So sorry for the confusion. It took me a while to figure out what happened and went wrong.
