An update for anyone that may be interested... Finally finished the job and, though the Lock Up solenoid looked NOTHING like the replacement, it seems to be working properly and the dreaded arrow is gone! As for the twisted off bolt, my fix for that would have to be explained in another thread but a...

So it still comes back to the same 2 issues. 1) The amp is bad and has a failed component and an internal short, or 2) The extra load the amp pulls over the SC-901 (which as no internal amp so it pulls a low current) is causing a short to manifest somewhere else in the harness. I have little to no k...

Mine does the same thing, I am running with no amp now, here is a recap of my less thorough experience https://www.matthewsvolvosite.com/forums/viewtopic.php?t=91281. Given that this failure is semi-common, my guess (!) is the amp. But good suggestions from Neil to just to rule out the harness - tes...

That transmission (I have it) does sometimes have a rough shift or two during normal operation. I've experienced the same thing occasionally on my original trans (lasted 280K before swapped due to large leak) and my current one (used w/~150K). I would just do a couple drain & fills with good tra...

The up to 98 (before the ETM came) are quite trouble free. Even after that they were not bad compared to say an Audi. There are way more troublesome cars to tinker around with. Up to 95 the 850ies had the OBD 1 blinky box which enabled you to diagnose car problems without an OBD reader. Plus, the 96...

I'm in the process of testing the effects of blocking those off.

Hello everybody ! After having some trouble finding an amp from a V70 I settled on a C70 4*100W amp (paid 50 euros with wiring harness and postage). After discovering not many people had attempted this and most of them didn't document the process I decided to do it myself using common sense ! So fir...

YES !


Absolutely, positively YES!

Add a Fuse at the battery!!!

If the wires short to ground between the amp
and the battery, they will Catch On Fire ...

There are fewer P80s in the world everyday.
It would be a shame to burn yours up.

You are on the block yo be voted off the P80 Island. Only a June has veto power from the tribe.

I have a safety related question.
Is there a fuse at the battery end of that large red wire?
Sooner or later, the threads it's rubbing against will short it
to ground, and after the fire, struts will no longer be an issue.
Just sayin'...
