Morelli Posted November 8, 2019 Report Share Posted November 8, 2019 Anyone with a volvo vnl 780 have their speaker stopped working except for the two upper bunk speakers ? My truck has a ton of speakers and they all stopped working. Checked all the fuses, controls are set correctly, amp plugged in. Rather stumped ....

Morelli Posted November 10, 2019 Author Report Share Posted November 10, 2019 Figured it out, there is a mistake on my volvo 2017 fuse spec sheet or wiring of the fuse center. Reminds me of my day working on mainframes where they used the same color wire for everything !! All speakers and amp up and running.

alan0043 Posted November 10, 2019 Report Share Posted November 10, 2019 (edited) Hi Pug, Something like that would drive me crazy. Did you go thru all the fuses to find the bad one ? A man needs to have his tunes ! 😎 Al Edited November 10, 2019 by alan0043 Quote 2012 Volvo VNL 630 w/ I-Shift; D13 engine; " Veeger " Redwood, model 3401R ; 5th Wheel Trailer, " Dead Wood " 2006 Smart Car " Killer Frog " Link to comment Share on other sites More sharing options...
Darryl&Rita Posted November 10, 2019 Report Share Posted November 10, 2019 The real question is, why did the fuse blow in the first place.

Morelli Posted November 10, 2019 Author Report Share Posted November 10, 2019 No fuses where blown, tested every single one and the radio fuses was not for the radio. The amp came unplugged and plugged it back in and still no luck so ordered a replacement amp. Meanwhile installed my GPS and Dash Cam while using Volvo B1-(1-6) wiring ports and plugged in the corresponding fuses. That is when I discovered the amp came back to life all the speakers fired up. I took the dash apart and the factory wiring has not been altered/tampered with so going to assume a mistake at the factory. Also trying to understand why some fuses where removed to being with. So far every test point I have gone through has checked out good, it looks like someone disabled some features/options by pulling fuses and relays. More to come later.

Morelli Posted November 11, 2019 Author Report Share Posted November 11, 2019 after spending some time checking all fuses to factory values (had several to replace) and making sure all relays where installed per factory requirements (3 where missing), everything works great. discovered the truck has 10 speakers and 1 sub and when playing my music, she blasts !! Gained a couple extra items too 😊 Quote Link to comment Share on other sites More sharing options...
