tach light blowing
« on: November 14, 2009, 02:35:11 PM »
the tach light on my 71 cb500 keeps blowing. replaced the bulb it lights up, seems fine for sometime, then blows some time later the speedo does not blow. The power for both comes from the  same power source in the headlamp bucket. checked for grounding but found nothing. all the other bulbs/lamps work fine.  checked voltage. any idea's.
