While on a traffic watch flight, ATC reported the transponder mode C to be off by plus 600 ft in my small aircraft. After flying the shift, I decided to drop off the reporter and ferry the airplane to sjc where a replacement transponder could be installed. After the reporter got out of the aircraft at hwd, I called ground control for taxi instructions. Ground cleared me to taxi to runway 10L. While taxiing, I passed some emergency vehicles on the field. The ground controller called for me to make a left turn and I turned right to give way to an aircraft taxiing to the emergency vehicles. I was more concerned about getting approval to fly the aircraft with the faulty transponder than I was about the emergency vehicles. What I should have done was park the aircraft and had the maintenance done at hwd. In the future, if emergency vehicles are on the field, I will request a route to taxi well clear of any areas that could possibly interfere with their operation.

Title: AN SMA FAILED TO FOLLOW TWR TAXI INSTRUCTIONS WHILE THERE WERE EMER VEHICLES MOVING ABOUT.
Narrative: WHILE ON A TFC WATCH FLT, ATC RPTED THE XPONDER MODE C TO BE OFF BY PLUS 600 FT IN MY SMA. AFTER FLYING THE SHIFT, I DECIDED TO DROP OFF THE RPTR AND FERRY THE AIRPLANE TO SJC WHERE A REPLACEMENT XPONDER COULD BE INSTALLED. AFTER THE RPTR GOT OUT OF THE ACFT AT HWD, I CALLED GND CTL FOR TAXI INSTRUCTIONS. GND CLRED ME TO TAXI TO RWY 10L. WHILE TAXIING, I PASSED SOME EMER VEHICLES ON THE FIELD. THE GND CTLR CALLED FOR ME TO MAKE A L TURN AND I TURNED R TO GIVE WAY TO AN ACFT TAXIING TO THE EMER VEHICLES. I WAS MORE CONCERNED ABOUT GETTING APPROVAL TO FLY THE ACFT WITH THE FAULTY XPONDER THAN I WAS ABOUT THE EMER VEHICLES. WHAT I SHOULD HAVE DONE WAS PARK THE ACFT AND HAD THE MAINT DONE AT HWD. IN THE FUTURE, IF EMER VEHICLES ARE ON THE FIELD, I WILL REQUEST A RTE TO TAXI WELL CLR OF ANY AREAS THAT COULD POSSIBLY INTERFERE WITH THEIR OP.
