Battery compartment components

[ljcpmc]

Decided to clean the batteries, cables etc and wound up in trouble. Pulled both batteries and tried to remove something - maybe a relay, a number U-21-H is stamped on back? - attached to the left wall and broke it. There are 2 (over and below each other) with red battery cables and the 2nd wire goes thru the wall. The local RV dealer advised me to call FR (do have a call in, waiting for reply) and find out the amps. Anyone know what this parts are and what amps they are? Hope this makes some sense. Thanks.

They are terminals strip. When the manufacturer needs to join 2 terminals together they use them. If you have room on another put your wires their..BTW relays will have more then 2 wires, what they control and controlling wires

Success - Forest River tech came thru, sent pics and he identified the components as 30 amp terminal relay/strips. Bought the parts today and will install sometime.
