Starting to hate my truck because of electrical issue???
I'm at the point where I honestly want to now get rid of it and get something else. Got the ranger back in 2010 (it's a 2001 XLT) Previous owner looked like he took care of it, it's nice looking and didn't really have any problems. I use it as my DD. I've replaced misc things like the blower motor, resistor..etc. Small stuff
Just a couple weeks ago I started hearing a high pitched electrical noise and my speedo would bounce... Replaced the negative terminal on the cable and the bounce went away and I also cleaned all the ground points in the engine bay.
While I did that I changed the tensioner, and put a new serpentine belt along with replacing the ac compressor and evap. Finally had working AC and it was nice.. but I then noticed that the oil pressure guage would jitter a little bit when the AC was on... read another thread and someone said that's the voltage drop. Ok fine... a couple days go by and I see my temp gauge start rising. I plug in my OBDII sensor and start reading the data and the coolant is reaching 270 degree's way too hot...
On top of that my battery gauge is low and below the battery icon sometimes almost barely above the low mark...
I get the following: New alt, new motorcraft thermostat, motorcraft water pump, and new upper and lower rad hoses and new front fan clutch. I completely flush the entire system including heatercore. I don't have any blockage as water goes in and out perfectly fine. Cleaned everything and then start to bleed the system. Have the heater on high and hot so it gets the air out of the heater core. Cold air for a while then it starts heating up.
My oil pressure gauge is still flickering, my temp gauge is still going up to H even though it's 230' degrees, and my battery gauge is low.
WTF is happening!?!? I'm almost ready to take it to the dealer and get raped by them as long as someone can fix this problem.
It almost seems like it is HIT or miss. If I shut the truck off, then start it back up sometimes it's fine and the battery voltage from the alternator is reading 13v... other time the batter is just at 12v's...
When I shut it off then tried to start it back up it just clicked, did this a couple times then it started. Mind you the battery is brand new.
Could it be a starter seloniod or starter issue? I even swapped gauge clusters and it's still doing the crap it was before.
My truck has been perfectly fine up until 3 weeks ago... I find it odd that all this is happeneing AFTER I got the truck aligned...
When I drive there is no hesitation or stuttering at alll I just really don't know what is going on with the electrical system?
ANY help would greatly be appreciated because at this point I truly don't know what to do but take it in and have them say welp, your entire eletctrical system needs re-done?
Could the loose negative terminal possible screwed the ECU computer in the truck or GEM..??
It's like I get 3 different results by shutting the truck off, and starting it and doing the same thing over in the garage, truck isn't moving so not sure why sometimes it's perfectly fine and other times it just acts like something isn't right...
