I found two burned out #89 bulbs in the flash circuit shown in the attachment. Also found the 330Ω resistor broken, presumably why the bulbs burned out. I have replaced the resistor, measures 330Ω and the 1Ω in series resistor also measures 1Ω. So before I replace the bulbs I checked the voltage across the two bulbs shown and measures 39V. This is in game started mode. Seems way too high, and won't it go higher when the "flash" signal is given?
#89 bulbs are 12V bulbs. I suppose they are good for 14V, but in series isn't that only total 28 voltage drop? Afraid to install new bulbs.
