    2019 Hino 338 power issue

    You were right, there was a missing connection to the leads. I couldn't even tell from the picture I took nor did I notice taking it off, but there is an all black wire that I left unconnected. Unfortunately I have no idea where it goes. An earlier reply mentioned 3 wires that all go to...

    2019 Hino 338 power issue

    So my boss actually went ahead and got a mechanic to come out and take a look at the truck. They verified that all the connections were in place properly and that we were getting power at the starter but there is no power inside the cab whatsoever. He remarked the strange polarity reversal at...

    2019 Hino 338 power issue

    I think I will just swing by the bay really quick and try this, however, why would the wire connected to the 100a have the polarity reversed? When I was checking voltage with the negative lead on the battery negative post and postive on the wire to the fuse, I was getting nothing. I decided to...

    2019 Hino 338 power issue

    I think I was only checking the battery side, and unfortunately I've had to stop working on it for now to start the workday. I did get a pic of the connections though. The lead on the positive side of the battery closest to the camera goes to a 80a in line fuse which I checked. The lead on the...

    2019 Hino 338 power issue

    Actually, if I put the positive lead of my voltmeter on the positive lead on the battery and the negative lead on the wires feeding the 100a fuse and 80a fuse, it shows 12.7v, so are these fuses actually grounded? Does this all check out so far?

    2019 Hino 338 power issue

    So I'm working on the truck today (happy holiday everyone) and got my voltmeter to check what's going on again. The batteries are hooked up correctly and power is definitely getting to the truck. And all the connections are made and working. There is power going to a few fuses but not to the...

    2019 Hino 338 power issue

    Thanks for the help again. I just checked 90% of the fuses and they were all good but ran out of time to do anything else right now. The two 10a ones on the far right in the cab fuse box marked "spare (ign-1&2)" were blown but not sure if that's the cause as I replaced them and the issue is the...

    2019 Hino 338 power issue

    Thank you for your reply. I think my game plan tomorrow will be to check all the fuses and since fortunately I have two other running 338s I can borrow parts that I know work to test. Should I disconnect the battery before trying to remove fuses from one of the other trucks? I definitely can't...

    2019 Hino 338 power issue

    Hello, I am trying to figure out what happened with my Hino. The original batteries that came on the truck were shot, I had to jumpstart it yesterday to finish the day and ordered the new batteries. This morning I replaced them with the new ones and put everything back together. When I turned...
