Ive blown an alternator on my TII because I only used one bag to protect it. I tested it before and after the wash. Before = 75amps After = 12amps

 

Just be careful and dont take chances.
I might even back off a bit on the aggressiveness of my washings too.

I didnt think about the idea that the Alt would not exatly DIE, but degrade.

 

Well I just did it.

I bagged off the alt., leading/trailing coils, clutch/brake master cylinders, airbox, and battery and put a towel over the belts.

I blasted the **** out of all the METAL pieces and used real low pressure on other old grimey things. Started right up and battery was at a steady 14V, as usual. Everything is MUCH cleaner and looks good. Finally my plastic/hoses are BLACK again instead of dust gray-brown!! You can see "Mazda 13B" on the side of the housings again (by oil filter).

 

wrrrr.... wrrr.... wrrr.....

 

I loves me those buzzy little beer kegs.

(I loves MAKIN 'em even more these days)
