Hi All,
I was working on my Milanos braking problem this weekend and found some intresting finds. When turning the key to the on position I didn't hear any activity from the electropump/accumulator and there was no pressure to the rear wheels when the brake was pushed. So the first thing we did was pulled the connector from the bottom connection on the electropump and checked the voltage. We measured 5V I thought that was weird instead of seeing around 12 was what i was expecting. The fact that i'm seeing any voltage makes me think that the fuses and relays are ok (although I didn't think to check these to be sure). The next thing We were thinking to put 12 volts to the electropump from the battery to see if it turned on but before we did this we noticed that the 2 pins on the electropump are effectivly shorted we were reading like 1 ohm across the terminals. This was a shocker to me and would be suprised that the fuses aren't blown. Is this a normal situation with a bad pump that the two terminals get shorted? I would have expected it to become an open circuit.
My guess is that the electropump is bad. Is the only solution for this to convert to the GM unit? I see that centerline has an accumulator but thats diffrent from the pump right?
thanks,
Bob
