hi I was wondering if anyone could help me.
I replaced all parts in my 6803 party animals power modules 5 volt regulator section, to try to fix 5 volt problem. but keep getting 16 volts at the test point 1 instead of 5 volts? all other voltages are reading correctly on the board.<O:p</O:p
<O:p</O:p

Parts I replaced listed below. These are supposed to be equivalent parts to the original used on the board.<O:p</O:p
<O:p</O:p

c1 :15,000uf cap 35 volts electrolytic capacitor<O:p</O:p
c4 :0.1uf 50 volt ceramic disk type<O:p</O:p
c5 :0.1uf 50 volt ceramic disk type<O:p</O:p
c3 :2.2uf 100 volt electrolytic capacitor<O:p
u1 :LM323K steel 5 volt regulator<O:p</O:p
R3 :2.2 ohm 1/4 watt resistor<O:p</O:p
R4 :100 ohm 1/2 watt resistor<O:p</O:p
<O:p</O:p

I believe this is all the parts to rebuild the 5 volt section. have I made an error? with the parts I have used. <O:p</O:p

The 5v regulator you installed could be bad. I have receved bad ones in the past.
Dobbel check your work! Replace the regulator. Try swaping it with a known good board.
Thats all I can tell you from here, good luck.
