Re: Volvo 850 GLT - Electrical power loss while driving

Sounds more like something is "loose", and excessive engine movement is causing the problem. (Based on your description)

Is the battery secured?

Engine mounts good? Grounds all tight and solid?

Re: Volvo 850 GLT - Electrical power loss while driving

I would look at the battery feeds first, then the electrical part of the ignition switch if that’s original

Re: Volvo 850 GLT - Electrical power loss while driving

It does seem odd that it would be the ignition switch at only 78,000. Still sounds like a loose connection or maybe a connection that somewhat corrodes or a relay that needs to be reseated after many years. A bad ignition switch would certainly cut power as described, but why under sudden decelerati...

Re: Volvo 850 GLT - Electrical power loss while driving

What DOESN’T make sense about that fix
is the radio losing power. Constant power

Re: Volvo 850 GLT - Electrical power loss while driving

The radio ACC power does go through the ignition switch via the X+ overload relay. At least if I'm reading the wiring diagram correctly. So it does make sense that the radio would shut off. Fuse 7 is the battery power and fuse 32 is the accy power for the radio. Now why it fully resets and asks for ...

Re: New Volvo 850 Purchase!

My daughter broke the original cup holder from trying to squeeze larger beverages into it. I purchased this replacement and it actually allows for larger cups since it uses opened circles and flexes a little more. Was very easy to take apart the armrest and swap them out. https://www.ebay.com/itm/V...
