Electric Retarder

[Stephen H]

HELP! Tonight I got my Retarder to show signs of working for the first
time. Every time in the past I have tried it, it never came on. Well, I
was messing around tonight at the dash with switches and The red
indicator light came on the dash, and the relays were clicking under
the bus in every position of the lever!! (I know, not too exciting for
most, but it has never worked before!!)I could hear a
diffrent sound with 1,2,3 and 4. The red light got a bit dimmer with
the next power, indicating to me that it was sending more, and more
power to the unit..?? All of a sudden, the light went off, and the
clicking quit. What in the world! I didnt even move in my chair, much
less mess with any connections. I could not get it to come back on
again. What would be a good thing to check first? Is there something to
cut power to this? I reset my breakers, and tried everything to get it
to come back.. I want my Retarder back!!! I had the engine/ignition
off, and nothing else on.
