    2012 Yukon Roof Rack Suggestions

    First, pull the plastic filler / plug off the end of front / back rail on each side. Then get a friend to help you slide cross bars backwards and off.

    Escalade Roof Rack and How to

    ...1 month later... A few thoughts how I have approached anchor repairs. We have these type of fasteners loosen occasionally on the LRVs I work on. My first approach is to use an ASTRO setting tool to see if I can 'seat' again after *gently* tapping back into hole. This implies can get...

    2012 Yukon Roof Rack Suggestions

    Was looking at the pads you mentioned, specifically #11. Looked at #6 too. And your Pic. If I understand correctly, the #11 fits all 3 positions, but the #6 does not? I really like the idea of the roads. A lot. So much so that I am tempted to commission a set of 'pads' for all 6 positions...

    2012 Yukon Roof Rack Suggestions

    Which rails? Not sure. Truck is an SLT, rails not flush, contact body at ends and middle.

    2012 Yukon Roof Rack Suggestions

    So, after using a silly cargo basket for a while, have decided to go a bit of different direction. Planning on removing sides, and shortening to 60" from 90ish.I hate the way the basket mounts to cross bars. Looks hokey, feels sketchy, though has proved to be quite secure. Only have about 75#...

    Dual Battery Build with Lithium

    Actually, I bought a pwm box that would allow me to set alternator output. Plan us to keep it at 13.8vdc. That yields (13.8 / 4) 3.45 cell voltage, compared to needlessly stressing cells at 3,65 (14.6v max charge). Also good with the 13.8v output as most things automotive are rated at 13.8...

    Time Delay Relay

    Something new noticed tday. While doing errands this morning, I happened to start my Yukon while in front of a bunch of glass. Noticed: Key on, no head lights. Turn over / Start engine, no head lights. Engine running, have head lights. At night, lights come on as soon as I rotate key. Still...

    Time Delay Relay

    I would love to have 'ditch' lights back! Project #5842. My wife's 2020 Tundra has auto and manual control of headlights. On auto, damn things stay on for 3 minutes. On manual, they stay on all night. Pickup will still start. Maybe I should just buy an old 3/4t 1980s model 'burb. Pre-fuel...

    Dual Battery Build with Lithium

    Finally got an assistant to help me measure starter current. Used a BluePoint inductive gauge (ol' skoolz here). 180 Amps with a still warm engine parked 20 minutes prior. That is the continuous current rating of a single cell, so 2 in parallel should be ablecto handle winter cold starts...

    Dual Battery Build with Lithium

    I know which one you are talking about. Tried it myself, epic failure. Did not pay attention to battery chemistry. That particular one was for 3.6 / 3.7v cells (IMR, NMC, IDK, POS, etc). I was using LFP, 3.2v cells. All ruptured their seals and spewed whatever evilness it contained. LFP...

    Time Delay Relay

    Ah shoot, I am dumb this week. No delay needed. Wire Headlights through NC pole of a 5pin relay, tie coil to starter solenoid engage wire, relay turns off headlights when starter turns. Much easier.

    Dual Battery Build with Lithium

    Just received (12) LEV60F lfp cells. 75Ah, max 600A output, 180A continuous. Will be building LFP battery exclusive for start (8 cells, 4S2P) and another for chassis (4 cells). Big things, though. Going to make some mock cells to figure out packaging and placement for start battery at passenger...

    Time Delay Relay

    Think I am going to shelve this for a while. Dual battery setup should accomplish same goal. The only delay relays that seem to fulfill the niche are based on 555 timers. While is an IC that I have a lot of experience with, and tolerates voltage fluctuations extremely well, another project may...

    Time Delay Relay

    Well, I know mine dim as engine turns over as are LED, and are bit sensitive to incoming voltage. No driver needed / provided. Most of the relay solutions I have found offer delay off, meaning output is turned off after x delay. It did dawn on me that I can trigger coil of another 5 pin...

    Time Delay Relay

    Anybody use time delay relays on their vehicles? Looking for a way to introduce a delay for Headlights turning on. Currently, headlights come on when I insert key and rotate to 'run'. Can see them 'pulse' as starter motor rotates. Want the headlights to remain off for maybe 5 seconds as...
