No power, battery is good
2004 Yukon Denali, two days ago went to start the
truck and nothing. No power whatsoever, no lights
or sound nothing. Battery is good. Didn’t have time
to work on it, came out the next day and it started
right up, drove no issues. Today, same issue no
power won’t start. Any ideas?!
I just had to rescue our 2018 rental from a no start/no-power issue With symptoms similar to yours. In our case the 175 amp buss bar integrated fuse was blown. Check for power to each of the buss bar cable connections. In our case, jumping from an adjacent (unused) terminal repowered the system. So we relocated the effected cable to the unused terminal and it was good to go again. -the buss bar is under the plastic cover on top of the battery. The black plastic bar on it encloses fuse points. They seem to wear out over time for some reason. Probably because its not a toyota.
