Aquast relay Ll814G

BigcatBigcat Posts: 6Member
Hi guys.

I have a old american stranded gas furnace that craped out.

I have had a serviceman look at it last season he changed the gas valve,it ran a month and now it's dead again, I called him he said it must be the valve again?.

Being a heavy equipment mechanic for 40 years, i figured I would check it out myself.I can read a volt meter.

This is what I have aquastat relay L1814g 

When I test the thermostat  lugs TV and T .27 volts  I can hear it working when I work the thermostat.

Testing circulator  C1 and C2 121 volts

Testing L1 and L2 121 volts

The B1 and B2 are dead .

My Question is what voltage should I have at the B1 and B2?

My next question is I have done a search and can not find the G model is the J a replacement?

Thanks for looking  John
