fUpon experiencing loss of flashers on my BJ7 I spoke to Blaine Graham of Moss Motors tech who gave me the following diagnostic procedure.

Disconnect left or right small wire from coil.
attach charger at low input to battery.

create test light from a bulb and socket connected to 2 14" pieces of wire.

verify brake lights work. Check terminal 5 if lights don't work to verify that relay is not to blame.

terminal # 1 is power in to relay. Apply test lamp to # 1 terminal. If light comes on but doesn't flash problem is in flasher

Connect to # 4 and #7, switch on column working.

Check #6 (to R front flasher, #7 to rear flasher (rh)

Check # 2& #3 (left flasher front and rear. If there is power bulb might be faulty.

Clean contact points in relay with fine sandpaper.

I hope I have relayed this info accurately. If still having problems contact Blaine at Moss Motors 800 667 7872 ext 3237.
 
Did you sort this out? I'm just now looking for something that is blowing my 35 amp fuse. I also do not have flashers. I'm going to look at your steps and see if I can'f follow them through. I haven't checked brake lights yet, but will. All oher lights work.

Disconnect all wires from the distribution side of the fuse ( leading to the various items of electrical equipment), replace them one by one until the fuse blows again - that will lead you to the cause of the problem. Mine was the wiper motor - brushes were worn down into the brush holder, commutator chewed up.

Thanks. Very helpful in figuring out my problem was the relay. Now trying to figure out if I should spend $120 for the new solid state version . . .

mike,
just open up the relay case and lightly sand the contacts to clean them up, adjust as needed to make it all work smoothly. It's a pretty simple device once you see the innards.
