wiper motor has no fuse?
I was looking at a wiring diagram for my 1977 Dodge W200. I noticed the wiper motor doesn't seem to be protected by a fuse? Why? On the actually truck I believe the only protection for that circuit would be the fusible link (in the engine compartment) or maybe the (15A?) circuit breaker (between the flashers). It appears to ****** power off a light blue wire which is the main power wire fed by the ignition switch.
The wiper motor is one of many circuits I plan to switch over to relay control but, it doesn't feel wise not to including a fuse.
So, the next question is what size fuse? I understand the motor will pull a lot of current when starting up or when locked up.
A 1986 Ramcharger calls for a 20AMP fuse... that seems like a good start.
If it blows I could up the size and carry spares... sounds better than no fuse at all.
Any suggestions?

I removed all the fuses and sure enough the wipers still run. So, other than the factory fusible link that feeds the ignition switch there is no protection that I can see.
From what I understand fusible links are more for protecting the wires than the devices connected to them. The last line of defense.
