Help identifying these electrical components

[rshackleford]

ANyone know what these are? They are on the frame rail near the starter on my 01 Journey 36DL. As you can see they are rusted pretty bad and I'd like to replace them before they cause me a big head ache.
There are two devices that look identical on the right, possibly fusible links or diodes?
Then on the left it looks like a solenoid or relay.

I was hoping to identify them so I can order new ones before I try to take them apart and clean the connections on those. Pretty sure the will break if I try to loosen the nuts.

You can buy them at automotive stores or RV stores. Look closely at the side for their amp rating.

you can get them at a big truck center there just big 40 50amp fuse they could be a reset type

it would nto hurt to just clean them and reinstall

Thanks for the replies.

any guess which wiring diagram I would find them on?

Are those installed by Freightliner or Winnie?

On my 2002 journey, this first is a 50amp breaker for the chassis, the second is the air intake heater relay and the last is a starter relay or solonoid. Mine are located on the passenger side frame rail opposite the allison. Many road shutdowns because first breaker breaks inside. Solve problem by attaching both red 12v cables to one post. This breaker has pressed contacts and fail often. Rkl

I'm thinking they are Freightliner , I'll check my wiring diagrams .
I know mine carry a 135 amp rating, the 2 fuses on the right side that is,
They protect the main 12 volt supply , battery bay to dash , one is chassis battery the other is coach.
99% sure the relay/solenoid , on the left is starter, intake manifold heater relay is on the engine on my Cat.
I'll go over my diagrams and update with any different info.

My wiring schematic, shows 1 ( 135 amp ) for the chassis wiring protection.
F/L may place the second one for use by the manufacturer.
F/L , part number 181135P010, old price of $23.14 ( Bussman Relay 135 amp is the other info)
If you call the F/L free help line 1-800-385-4357 have your serial number handy when you call.
Ask about joining " Access Freightliner " for online parts, wiring and other info, takes a few weeks for clearance , but well worth the wait.

Just bought an 02 Winnie Journey this spring 48,000 miles. Been great but just hit a big pothole and dash lights flashed, gauges crazy, continued for 200 miles off and on to home. Now engine will turn but won't start. I assume I need to replace the 135 amp circuit breaker on frame. Do not know where to look and how will I know it.
