SLA charger resistor values

Two resistors (in parallel to each other) burned out and have shorted. I
continued using the charger and of course now my battery is damaged.

I think the resistors are in series with the transformer, a voltage
regulator (i assume) and the battery. There is a PIC among other stuff but i
cant work out how that is connected.

I want to try replacing the resistors but they are so burned you cant see
the values. How can I find out what the value of these resistors are?

I have no idea where to start so ill just read what is says.

PCB reads ©TREMACO PRODUCTS IBC-1 REV1.0 1998

Cover reads
Float charge 13.7V
Bulk charge 14.5V

Model C1.5A12T
made in UK by tremaco

I use if for charging a 12V 7Ah battery. If anyones intrested i got this and
the charger from Rapid Electronics


any help would be greatly apreaciated
