Amiga 3000T Low voltage on RTC

[Kawazu]

Hello.
I have just changed the battery on my A3000T to a coincell and im having a bit of a problem.
Pin 18 on 190 is only getting 0.5v

When i messure the voltage on the leggs of the coin cell adapter before i put it into the motherboard i get a nice 2.8v
But when the adapter is placed in its holes on the motherboard and i messure the voltage again i get a 1.73v
And after the R192 resistor it drops to 0.52v

The voltageshould be lower after passing the resistor but why the hell is the voltage dropping from 2.8v to 1.73 on the legs of the adapter when i just place it in its socket?

Reminder: Check that you have placed the coincell holder on the adapter pcb the correct way so + goes to + and - to -

I thought that this meant he had realised that the battery holder was the wrong way around on the pcb giving reverse polarity, hence my comment that he had already fixed it.

Kawazu: Did you fix it ? :drink:

Yes i did indeed "fix" it
Have 2.8v on pin 18 when the amiga is off and she is keeping the time :roflmao:
