Glow plugs / Relay

[ragedracer]

M1009 been a little slow to start on the colder mornings here. And were only talking like ~35 degrees. Not really cold. So, I followed the wiki and first thing pulled a wire off a GP and read it with my multimeter when the key was turned on. When the relay initially clicked, I got ~23 volts, which pretty rapidly settled down to ~17 and stayed there for each additional time I cycled it. Is this normal?
I'm sure I need new GP's, since they are getting voltage. Wellman 070's right? The guy on eBay ok?

Next Q. I also read the wiki and it seems I may have the old GP relay that should have been replaced. I attached a photo below. Should I replace that relay when I replace the GP's or just leave it as is?

Ebay guy is great for the plugs.

That relay looks just like mine. I think the 'old' one is plastic.

That is the newer style relay.

Thanks! That will save me some dough. If you look at page one of the CUCV faq, someone posted photos and said "if your relay looks like the one in last 2 pictures, its bad". Well, mine looks like the one in the last picture.

Either way it seems to work fine, its just the glow plugs that are worn out.
