Any pros to help!!

Volt on the dash would drop from normal to low when I come to a stop. I got home and parked the truck. Came back out and she doesn't want to turn over.. I put a jump box on it and came up to 9volts, turned the box on and jumped to 12.6. So I headed over to pepboys and had them replace it. She looks good now. But my question is, now that I have replaced to alternator, my dash and running board light look like they pulse in a way. What could be the problem now??? Thanks

Electrical connections - possible broken wire that doesn't show from the outside.

Troubleshooting time, how are you with electrical work?

Does it only pulse at idle?

possible connection issue, possible failing voltage regulator on new alternator.

did you get a reman alternator or a brand new one? do you know how to check electrical connections?

Not a big fan of electrical. That's why I had it checked out. I don't know the name of the alternator replaced. Nothing but problems with this ford.

Take it back to them since you should have at least a 90 day warranty.

can you read and understand electrical diagrams?
how well can you use a test meter?
what are your mechanical skills?

My truck is doing the same thing with pulsating lights. Stopped when I changed the alternator but now its back. Thinking its poor quality regulator. Drive works special...
