My battery lights comes on after driving for awhile .

they said it was the cables so they cleaned and
tightened . Had van back 1 day and again light on
plus the abs and esc lights flashing . So back it
went . Replaced the Alternator this time said it was
putting out to much voltage. Picked up same again
after driving about 39 min back on . 3 time there
said bad cell in battery . Replaced battery picked
up drove to work next day , 30 min in to drive
battery light back on. Just dropping it at shop today
for the 4th Time getting a little upset now .
Does anyone have any idea what this could be ?
Van starts up every time with no problem with no
battery light on , until you drive for like 30 min then
light comes on

Sounds like something is getting hot and causing the light to come on. Try this, drive the vehicle without turning on the heater. See if the light still comes on. If not, I'd suspect a faulty instrument cluster. If so it's in the engine compartment. I hope the shop is troubleshooting this when the light is on. Trying to troubleshoot it when the light is not on won't work! Hope that helps! Jim

Thank you for your advise . I’m pulling my hair out slowly over this . They do plug in a scanner to read the codes every time I bring it back . I leave it running so lights on . I think it’s a wiring issue, but I’m not a mechanic. Let’s hope 4th time lucky on Monday
