520H, 1994 Switch Relay, Start Relay Locations??,

[Chuck14025 9]

Can any tell me where the switch and start relays are hiding on a 1994,  520H? Also, what is the small switch on the back side of the battery box that has a rubber tube hanging out of it?

The relays are well hidden behind the battery, if you need to work on them it is easier to remove the belt guard on the right and go in that way.

 

The “switch” with the hose is to check the restriction of the air filter and turns on the light in the dash.  That switch is expensive and very easily broken.  The hose connects to the bottom of the air filter housing.
