1987 r model clutch pedal making voltage drop (dynatard)

[Ericjdecket]

I'm getting a weird voltage drop and buzzer come on when i lightly depress the clutch about half an inch. To my knowledge there shouldn't be any eng brake switch on the clutch bc its not a jake setup. I removed all the panels i could and didn't see anything hooked up. couldn't find any wires rubbing on the clutch assembly or anything. really confused with this one any advice appreciated. Video attached

Hmm.  I need to think on this one. Did you look outside starting at the firewall and follow the clutch cable to the release arm? Did you check the small cab ground wires behind the cluster to see if they are tight ?

this is too new for me teacher ; question I have is : does this have any relationship to the dynatard? stepping light pressure should disconnect the engine brake ??NO? does this happen if engine brake switch is off?? wouldn't be a bad shorted out solenoid , depressing pedal should cut engine brake.. chafed wire some where's along clutch linkage path ??

He said that he doesnt have a jake brake (common terms not knowing about dynatard) .  We only see the alt gauge drop off, and no other reactions from other gauges, or lights, or ???  Its vague.
