Hi All,
I began having a reset issue with my Taxi. This would happen during gameplay and also once warmed it would randomly reset in attract mode so I am going to rebuild the power supply as it appears all original from looking at the back of the board. I have reset all connectors and made sure ROMs were secure. I did take some readings prior to removing the board at some test points and the +12 seems far too low.
Here were the readings:
TP1 +5V = 4.92
TP3 +12V = 9.08
TP4 -12V = 14.7
I plan on replacing listed capacitors:
C1 & C3 which are 220uf 160V
C10 which is 18000uf 25V
C8 which is 47uf 63V
C9 which is 1000uf 25V (this one looks suspect)
C7 which is 100uf 25V
C12 which is 330uf 10V
I will also reflow all header pins at J1, J2 and J3....headers and connectors look good (no browning on connectors)
I wanted to ask the group if I am headed down the correct path and if I may be missing something else that should be replaced during this rebuild? Thank you for any assistance.
