Jump start the car, let the battery build up, for a minute or two, than take the cables off and wile car idling remove any of battery terminals, if car engine stops running, You ll have an alternator problem, or a voltage regulator, in today's cars, the voltage regulator is mounted inside the alternator, in does days, perhaps is outside some place on the engine fire wall

Check your Belt and see how tight it is. It may be Tight just not tight Enough to Fully Charge the Battery with the Alternator.

1999 3.2l. Why are battery and brake lights on?


was not on before the new alt,? is alt new or used.?
or came on only after the new ALT?????????
my guess, is 2 failures.! (one ignored and 2nd grew)
on with engine running, guess yes.
Good question and is same answer on all cars.
1: engine rpm too low, what is yours (below 80 rpm)
2: fan belt slips. bad tension pulley (weak and old???)
3: Alt bad, or its wires bad.
4: brake level low, (@MC) or hand brake switch stuck on, or other brake failures. a plenty, scan the PCM and ABS if you have ABS.
id not drive it with the brake lamp on (Savvy?)
the battery light is really the ALT charge lamp.
it glows anytime the Charge system can not charge the battery
if you drive far like that, the engine will stall and not crank.

5: the horn fuse power the alternator, so check the horn fuse
10amp , key on, 12vdc on both sides of fuse is needed/
fyi: the meter fuse runs the charge lamp, if said lamp is dead bingo.
6: fact 2, the PCM does NOT run the Alternator on the 3.2L .
7: alternator case not grounded right.
8: battery is bad, causing alternator to drop off line
9: battery cables bad, at the 4ends or they are bad.
10: the plug on the rear of alt is bad or its wires or pins rusty.


brakes:
the brake lamp has 3 inputs ("OR" logic) master cylinder level low.
the hand brake lever and the EBCM (electronic brake control module)
a technician unplugs each to see what causes the error.
if you unplug mC wire and hand brake wire
then the EBCM is UNHAPPY, scan it.

No charge on battery


I would have the battery checked to see if it is not the problem first. If it isn't working right you either need to pour water into the battery cells or just go out and buy another one.

How to change under-hood fuse in a994 Mercery Villager


you have fuses there and in the van by the drivers side instrument panel.

here's how to change,
Fuse — Main Fuse Junction Panel NOTE: The MAIN and ALT fuses are high ampere cartridges that are held in place by screws, which must be removed in order to replace the cartridge. For removal of the MAIN or ALT fuse, refer to the procedure in this section. Always replace a blown fuse with a new one having the same amperage rating.

Removal
  1. Remove the appropriate fuse panel cover (14A003).
  1. Pull the fuse straight up from the fuse junction panel (14A068). If the fuse is a cartridge-type, carefully pry the clip, then pull the fuse straight up.
I would also check relays, including inhibtor relay. relas have a relese tab.
