Cucv won't start

[AJMBLAZER]

I only use distributors I know are reliable and will accept returns and even pay for return shipping of defective products. Ebay is created by the internet and is not real so if you pay for something there is no guarantee. I would feel safer spending my money on lottery tickets and newports. If I am going to spend 100$ it is going to be for the correct parts that were designed specifically for my application.

The Wellman's ARE designed specifically for the CUCV's.

One of the vendors has an internet storefront. I bought mine through them. Worked great.

Go with the old school 13g's...just hope they don't swell on ya.

I bought mine from SS Diesel Supply, no problems with them, but only bought this so far.

I have purchased a few things through the net, I dont do ebay either. But one thing I have learned on this site, these guys will do their best to look out for each other.

So u can buy from your local Napa, or online.

A set from SS is like 80 bucks plus shipping iirc.

New glow plugs in tonight and she started right up! Thanks for all the help and advice.

Nice! Did you figure out what needed to be fixed so as to not blow out your new plugs?

 

[Richcz28]

Put the meter on them and everything seems ok. Correct 12volts. I think that too many bad plugs caused the resistor to not resist because it had no load.

Also if anyone is curious the old plugs were wellman 070s. They looked like they had seen a fair amount of service judging by the heat element and rustyness, and I'm guessing their number was up.

Colby, his system sounds like it was working correctly. The CUCV setup sends the same amount of juice down to the GP's no matter how few it is divided up amongst. So the fewer you have functioning the more juice goes to each working GP.

Went back and checked the volts again to make sure. Around 10.5 - 11 at every plug. I plan on checking them routinely for resistance so I don't run the risk of frying them all again. My resistance on the new plugs is right around 1 ohm.

The easiest way, if you have a meter than can do this is, is check the amp draw on each bank. The glow plugs (IIRC) should pull about 4 amps each so the amp draw per bank is 16 amps. And if I remember this right that circuit has a fusible link for 50 amps.

BTW those specs work on a ford powerstroke as well. A clamp style amp tester makes it fast work to diagnose hard starting on a ford....

The easiest way to check your glow plugs is with a test light. Clip the alligator clip to the positive on the battery, touch the probe to the spade of the glow plug...no light, bad glow plug. Easy enough to do as part of your regular maintenance.
