Do you know the tipical problem went the battery runs empty after a short while

just buy this car like that, not told any history.?
never have I seen any IMMO security failure allow engine to run so my guess means doors ajar or the like.(only, body alarm stuff)
battery lamp means alternator is dead. charge lamp. it is wired directly too lamp to alternator pin.
it means ALT is bad, or its fuse to it blown
or battery cells shored, and ALT goes off line to prevent battery explosion. (ruptured and ACID all over things horror)

if cranking sounds normal the battery is ok for now , but will die soon.. 13-15vdc at the battery car idling
if lower volts ALT is bad, or 3 fuse blown to it.

WHEN THE CAR IS RUNNING PULL THE GROUND OFF THE BATTERY POST CAR SHOULD STAY RUNNING, BATTERY IS ONLY FOR ACCESORIES AND STARTING THE CAR, IF IT DOESNT NEED TO REPLACE THE ALTERNATOR

Alternator is not charging, if you got a reman it should be under warranty and if a shop put it in they should be able to test for free

if you know someone with a code reader you can get codes. could be your battery shorting out. check your grounds . battery to frame and to body of vehicle.

Tipical for that amp.Did you buy it used?

sounds like a short, or grounded wire,maybe connectin lose on battery or starter, could be a bad solonoid on the starter,did you check to see if parts were new or used, they have to warranty the work, so check first if parts are new and then take back to have it tested and repaired make sure you have some one with you or take pictures of the work done, hope this works for you,,,

yes you can run in your gym, any machine is global attached by ISO 9000 + etc , and there are conditions for tipical voltage in many continents like North America, latin america, etc.

In short you can connect your tredmill in 120VAC(alternating current) or AC only you must provide a good circuit for protection with the require dimension wires + ampacity of breaker.

1st you have a tipical virus syntom, any antivirus instaled? check status on online antivirus, like : norton online, macfee,....

check the Ignition Starter Switch (tipical on tb)

Some of that water must have gotten inside amd shorted something. If this is less then 1 year, it would be under warranty. It iwll have to be taken apart and checked.
