Battery ?

[Good Stuff]

If my T190 sits for a few days the battery is week and wont start the machine. Once I jump start it and run it it will crank fine. I had the battery tested and they said it was fine. Could something be drawing the battery down when it's off and how could I test to find out?

Do you have any aftermarket accessories installed ? Like strobe light, fog lights, radio etc ?

No.

Even a bad alternator could cause power drain.
Try disconnecting the +ve cable from the alternator while shut off, tap the cable to the bolt on the alternator and look for a spark, if it is, there is your power drain.
If not, you can hook up an amp meter bwtween a battery post and the battery lug. You can then remove fuses till the power drain is gone, then trace it from there to see what is pulling the power.
