Thank you, Mr_Reverse! I will work on current testing alternator, but, since its making those noises, I am likely to replace it and the idler pulley on general principle.

I have a brand new Denso/Bosch starter, and I will be installing it today as well, since I have to get down there for the far end of the positive cable, anyways. The positive cable does not look like a lot of fun to install.

Thanks, Mr_Reverse. I appreciate your reply. I *should* have prefaced the situation with what I know/have done. Load tested battery, it specs out *better* than its rating. I tested voltage at battery with the truck running, and the alternator is delivering rated output (I would like to point out that there are clunks and squeals and some grinding noises coming out of the alternator occasionally that disturb me, but I am never up on the battery terminals when this happens to see if the charging current changes). I have jiggled every wire, terminal, relay and fuse that I could touch. I have roughly jiggled both of the relay boxes under the hood. I have replaced the ground cable with a factory new unit. I have the factory positive cable, and I will install it today.

Hey guys, forgive me if this topic has already been covered. My truck is doing two "strange" things. The first is every now and then, the engine dies and all of the idiot lights on the dash light up. This happens for about 1/4 second, and then engine resumes and the lights go out. Then yesterday, it started idling choppy and the Check Engine Light came on. When I got home, I scanned for codes and got P0120, which the online OBD resources say is: "P0120 is the generic OBD-II code which indicates that the Engine Control Module (ECM) has seen the TPS sensor circuit A output voltage going below or above the sensor's expected range, or is chattering when compared to TPS sensor circuit B." I am guessing this indicates that something is wrong with my TPS? The truck is a 1998 Pathfinder, automatic tranny. Thank you in advance for any guidance!

XPLORx4: I am so jealous that you have the Japanese projectors. They are sooooo much better than the SAE reflectors that North America got. I am going to add some kind of aux lights to try to assist my factory headlights.

For what it's worth, these are the only LED replacement bulbs I have found that perform better than conventional halogen 9004/9007 incandescent bulbs: https://headlightrevolution.com/9007-9004-gtr-lighting-ultra-2/ None of the other LED replacements seem to get the chips in the right place for 9004/9007 reflectors, and I have seen horrible results with any/all of the sub-$120 LED replacements for 9004/9007. And, those GTR bulbs are pretty spendy. In my opinion, a pair of higher efficiency bulbs or higher wattage bulbs and a relay upgrade are much more financially sensible (as several other guys already mentioned).
