Check your model #.. You can also hook a voltmeter up to the 12 volts and measure it..
I swapped out my original single stage converter in my old Mirada a few years ago.. If I were doing this again, I would not remove the old converter, I'd just disconnect it (remove the power and 12 volt wires) and mount the new three stage converter on the floor behind it and wire it into the system..
The new converter didn't boil the batteries, I left the MH plugged in year round when in storage.
The other advantage is the multi stage converter will charge the batteries much faster than the original single stage.
I did a short article on my blog site, with the part numbers and show how I did it..
