[Spits] OD fuse

[Joe Curry]

Grant (what a great last name for a fuse related issue),
What you are describing is a classic short to ground situation.  When you
turn on the OD switch, the short is causing too much current to go through
the fuse and it blows.  The short cold be anywhere in that circuit including
the OD solenoid itself.  To find the trouble, you will need an ohmmeter to
trace where the short is.  By disconnecting the wires one at a time anc
checking for continuity, you should be able to locate the problem.

Subject: [Spits] OD fuse

Hi everyone
I have a problem with my OD. The top fuse will blow as soon as I move the
switch to turn on the OD. After that happened twice I didnbt use the OD
anymore and the fuse stayed good for the rest of the weekend. I canbt see
anything wrong with the wires or the switch. In the garage I have moved the
wires every way I can and I have moved the switch to turn the OD on and off.
No blown fuse. Would that be different then if the car was moving??

I am thinking of putting a separate fuse for the OD so that if it blows it
will be only the OD that stops working. I think the fuse should be on the
Green wire not the Green and Brown .
Thank you for any help you can give me.
