Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
I've seen them use this trick a time or two ! Though sometimes the hour meter is correct ! You just have to go and inspect the item every time.You are not getting a great buy on low hour heaters! Many are scavenged or worn out! I bought 5 and only one was complete from Bragg last year. They all had either < 5 hours on them. 2 were 1 hours units! The disabling of the hour meter is one of the first things done by the Army! GL wants a premium for anything with low hours. Buyer beware.
I dont see where I replied about these K8 relays, my little research book notes are as followsthe two diagrams are above are of the k8 and commercially available White-Rodgers 668-415 kwik sensor.
they seem to be very similar no??
what do you think
Soooooooo, i haven't messed with this heater since last year. But to give an update i found this a white Rodger thermo swich on ebay part number is 668z-671 - its got all the same color wires white black red and orange. All the same labeled terminals.I dont see where I replied about these K8 relays, my little research book notes are as follows
Type 668..... 956 type flame detector used
type 668().... 60 hz only
type 668(h).... 50/60 hz
type 668-(401-499)....safety shutoff time 15 seconds
(501-599).... 30 seconds
(601-699).... 45 seconds
I have not found any White Rodgers that has the red/yellow alarm wire, if someone has found one that is not pn 668z-670 point it out to me. So my guess is that is what the 'Z' designator is for.. red/yellow alarm wire.
The data sticker on the K8 does not jive with the rest of any of the White Rodges controllers. The data sticker shows 45 sec, but the pn is a -670, so I dont know what to believe, unless its a special that does not follow general pn's.
