SMT750 AVR relay weld fault

[Anonymous user]

I got this error after replacing the RB48 battery after 6 years of trouble-free service. Internet chatter says this is a common problem, often when replacing the battery, and the relays aren't very robust. I'm fully able to replace the AVR relay if that is in fact the problem, but it would be a lot easier if I could find the circuit diagram for the SMT750 and/or specs and/or industry part number for the relay. Can anyone help?

Well, the relays test fine on the bench, but since they're only $0.64 apiece (maybe there's a lesson to be learned here), I'll replace them all and see what happens.

Replaced them all with no change in behavior. Any ideas out there?

Is it possible that you can provide me with part numbers for the relays so I can get replacements? Do you happen to know which one(s) is for the avr?
