Dura is asking about the breaker mounted to the dash, where the amp and hour meters are.
Type Walker Manual into computer, then look for Walker Resources, open it, click on support, click on model, scroll down for manuals. Have your serial number handy when you do this, as most of the manuals go by serial number and not the year the machine was produced.
A manual can start at year 1995 at serial #123478 and go thru to year 1997 ending in serial# 124478.
The next manual would be issued in 1997 starting with serial # 124479.
Any production changes between the 1995 manual with serial numbers of 123478 thru 124478 will be reflected in the next issue being the 1997 manual starting with serial #124479 this is where you will find you diagram.
They do not reprint a manual every time something is added such as your breaker or a configuration change, they wait a couple of years, compile all the changes
and issue a new manual, which in general is just an update of the previous manual with all the changes added in.
