for history of this thread, go to "what did you do to your truck today"
resume :
1-
2 month ago, battery low ; controlled it and alternator produced 18Ah when engine ran ; so I changed the regulator (LMC Truck)
2-
put my new regulator, and changed battery for a new one
3-
after 3 little trips, battery low ; I don't drive with lights during day
4-
yesterday, charged my battery (13V), started engine, and ... 13

question :
is it a problem with alternator ? regulator ? what kind of test can I do now ?
