Constant battery draining, found the source 850

Hi all,

Completely dead battery, it happened suddenly like that last thursday without apparent reason. Recharged the battery but it was completely dead again by friday. Removed the glovebox and trunk light bulbs just to be sure, no changes. Swapped the battery with the other car, same thing.

After I've read some posts on this forum, I used a multi-meter and found that I'm constantly draining 1.6 amp from the battery. By comparison, the standby current drain on the other 850 is about .025A (25mA)

By your suggestions, I removed the fuses one by one and measured the current drain in order to isolate the faulty circuit but again no changes.

In desperate, I've separate the 3 wires bolted together on the positive battery terminal and found that the 1.6 amp current drain is coming from the big wire, the one that goes to the starters solenoid.

Could the solenoid gets leaky after all those years? Is there something else that I could check in this area? Cranks perfectly otherwise but the starter ass'y is original, 22 years & 188K on the clock.

Thanks guys
