W201 dash warning lights on
Was driving today when all the lights turned on. It's a 92 190e 2.6 alternator, battery and plugs were changed about a month ago. Any input is appreciated.

Also wanted to say that the reading on the multimeter was around 12.7 on the battery when the car was running

Hi Insame1, i picked up the alternator from a local parts distributor - carquest - and the battery from Walmart. The battery is larger than the standard side as an FYI - its the 900CCA - same size as the one in the newer C classes. Generally, i always go OEM but was in a bit of a bind this time and didnt have enough time to order the parts on autohausaz. Do you think this could be causing the issue? I also ordered a new OVP relay from amazon: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Changed the alternator today and the battery, lights were off for a bit and turned back on tonight, any suggestions?!
Update - Installed a new ground from the engine block to the chassis which seems to have solved the problem. 100% due to weak alternator. Suggestion to anyone experiencing this problem replace the OVT and the Alt + new ground from the block to chassis & new ground from battery to chassis.
new problem is to figure out a way to tighten the drive belt..
