Got a multimeter, went to test my glowplugs a la Diesel Giant's tutorial, and can't stretch the negative probe to the battery and simultaneously test the glow plug ports (they are on opposite sides under the hood). What do you guys do, use an extension wire wrapped from the negative post to the multimeter?

Little obstacles....


I'm pretty sure my glows are in a bad way; it was 40 degrees today and I had to crank three times, 10 to 15 seconds each, before it would turn over.
