Charging System Questions
I am sorry if this has been posted but a 2 hour search answered most of my questions but I still have a few.
1. Will removing any of the relays under the steering wheel cause the batteries to weaken and/or alternator not to charge.
2. Would driving it for 4 or 5 days and parking it for 2 or 3 cause the batteries to drain. (when I drive it its at least run for 30 mins, and when parked its not started at all for 2 or 3 days).
The reason I pull the relays is, someone tried to break into it and drive off with it about a month ago, and I cant afford a quality anti theft device (I am considering a Revelco). Since then I pull the relays IDM, Starter and PCM Power relays. Around this time I noticed the batteries slowly weakening each time it starts (both less than a year old) and once in a while the battery light comes on for like 30 secs then goes off, so after parking it for two days I went to start it this evening and it barley turned over, I jump started it took about 10 mins ran it for about an hour and a half non stop (went to autozone got a battery brush, some cleaner, a battery tester, distilled water and baking soda). I got home and checked the alternator and got 11.5v to 12v, turned it of disconnected the batteries cleaned them all off along with the connectors tested them seperatly and both got 10v. so the altenator is not charging the batteries, the batteries were weak but the truck started will run for hours. I pulled off the alternator and batteries will have them tested tomorrow. I have owned this truck since new, the original batteries and alternator went out about 3 years ago, so I replaced them with motorcraft parts (expensive) and got 2 years out of the new batteries and replaced them under warranty last year.
So is it coincidence that this happened, have the parts lived out their service life, whats your opinion?
