04 quest van limp mode and no electronics
Working on a 04 quest. My first stupid mistake was not disconnecting the battery. I was changing the O2 sensor and the rubber boot on the alternator slipped up and the socket grounded the positive lead to the alternator. There really was not a spark, but there was a quick puff of smoke. And a slight pop from the battery I believe. The van starts but no electronics work except for the display. And a bunch of dummy lights are on. In park full throttle only revs up to 2k rpm and in drive or reverse on flat surface will accelerate but if I encounter a hill lit will not go up. Reverse is the same. No acceleration. Looks like the fuses are all good. Would the grounding out the positive wire cause the alternator to go bad? Which in turn make pretty much everything not work since the system is pretty much all electric? I have hooked up a code reader but there are no codes that have to do with electric. Needless to say I still need to replace the O2 sensor. Thank you for your help.
Ty for your quick response. But I was able to figure out the problem. There are a few in line fuses on the positive battery cable at the battery terminal. And the 40amp fuse was blown. I have also replaced the 02 sensor.
