I tested both coils (part 6717706) at 3.5 and 3.6 ohms … Bobcat manual says 5-8 ohms so as a first step I'm replacing both coils …Oddly I didn't feel any magnetic pull from either coil when I tested them both with the machine keyed to ON (not started) then using the right thumb switch. Same thing when I keyed ON and put the auxiliary hydraulics on (not started). Because the auxiliary hydraulics have been used in quite a few years, I'm also concerned that one or both of the Solenoid stem valves (part 6676249) might be stuck. Any advice? Did you solve your auxiliary hydraulics issue? Thanks</p></blockquote><p></p>
