I am having some annoying issues with my Montero Sport.There seems to be some kind of electrical issue or power distribution issue.Which is causing the vehicle's dash and headlights to have a surge in conjunction with the motor.Lights will dim and brighten as the engine sputters a bit.Also the vehicle seems to run fine once I'm at 65mph or more.Sputtering issues occur mostly between 10-45 mph.Electrical surging seems to be most common when sitting idle.I've had to change alternator twice in 2 years as well.I'm kinda at a loss now.Being a single dad is tough and now this.Any help to be offered would be so appreciated.

Suspect engine ground need to OHM check or voltage drop test. Do you have a DVOM? if yes check open circuit voltage at BATT see if it is steady 14.5 to 15V
