I've read here that one functioning glow plug will give you a "good" test if you only test to the common bar they all share.  You could have three bad 'uns there.

hi Roger
I get +13v with tester grounded to the *head* and direct jumper from  
batt to GP bar, so GPs should be getting good juice
any thoughts on ether/starting fluid as a stop-gap measure until my  
new plugs get here on the 25th?
or plugging in the heater overnight? (not going to get the combustion  
chambers hot)
thanks
