Blows internal fuse
by: Doug in s.d.ca.


How much of that first five minutes was it actually pumping?

I can't tell from the drawing what kind of motor it has. Can you tell if it uses brushes,, or is it induction (no direct connection to the rotating part).

What type fuse did you use for replacement?

We can go from there.

Blowing fuse
by: JP

I have a harbor freight hotdog compressor item 69269, oil less 3 gallon by central pnuematic. First time i used it lasted for 5 min before it blew its own fuse. Replaced the used, turned it on...nothing...blew the fuse off the bat. Tried another outlet after replacing fuse, same thing. Bought it brand new and too late to exchange under warranty. Please help.

60737 blowing fuses
by: Bill

Perhaps you might also let us know the distance to the socket into which you plug the compressor and the power panel that has the fuse is, along with what amperage is the fuse you are using.

Is the fuse a regular one, or a delay, do you know?

60737 blows fuse

Before you plug it in again, try replacing the fuse and use your free HFT multimeter to check across the parallel blades of the plug, switch ON. note ohms. will be a low reading.

Now disconnect two wires closest to the motor. Measure at the plug again. note ohms. should be infinity. Now, connect the wires you removed from the motor, and measure as before. Should lower that when you had the motor connected.

If that's not true, please look at the motor, and tell what kind it is, e.g., does it have brushes?

I have the 60737 and mine ran fine the first time I used it. The second time it blew a fuse when I hit the power switch. I put a new one in and same thing happened. Plugged using both straight to socket and another to extension cord

blows fuse

When? (as soon as you turn it on, after it tries to restart when air get low, or ...?)

Are you using an extension cord? Test without it.

What model is it?
