Peerless boiler w/ Johnson controls ign. module

[KEWROCK]

Hello forum, We meet again. Hope eveyone had a nice holiday.

I have a Peerless Boiler with a Johnson Controls ignition module #G600AX-1. Tonight the igniter stopped working. When I openend the back panel to clean whatever soot or scale might be on the electrode I noticed when I swiped the wire toothbrush across it I did get very weak sparks. Almost static, not the nice hot quarter inch arcs I used to get. Ordinarily the gap between the electrode and the gas collector for the pilot(ground) is a quarter inch, I bent it in to roughly a sixteenth of an inch. Now I do get a constant spark, but it's so weak it can't light the pilot.

Is it a bad module or do electrodes or maybe the silicone lead stop conducting? The replacement parts for these two joined companies are two to three times more expensive than other boiler companies like Honeywell or Carrier. The silicone wire alone is $70, ignitor assy 175 and module 300. So I really just want to change the culprit. 

BTW I read the section stove and dryer ignitions before posting. If I connect a multimeter from the electrode connector on the module to ground should I get 15000 VAC? (Couldn't do yet, dead batteries)

all contacts nice and tight and good burner ground to brain?

Yup, That's the first stuff I checked. I also checked spark intesity at the connector on bottom of the module where silicone lead attaches. it's the same, very weak slight spark at about a 16th inch from ground. That should rule out the lead and electrode I guess? could it be the transformer not feeding proper current to the module? It should be 24v. I can't check though, my multi's dead. but if that's the case the flame sensor shouldn't work, but it works fine. as soon as I hold a match to it, it opens the main jet and the boiler fires up for a cycle. It's got to be the module. I'd just hate to buy it then find out it was something stupid that I missed.

can't do that with a multimeter  :spaz:
