Noe of my W123's have the after glow GP timer, was it perhaps a cold weather area (like Mid West ?) thing ? .

I too would be looking at the alternator's regulator and brush holder as the brushes simply wear out over time and are dead easy to replace albeit not out side in the snow....

FWIW, I experimented with many different aftermarket brands of these and _only_ the BOSCH or HELLA branded ones charged to 14 + VDC .

man claim the German HUCO ones ad others do but they don't ~ I put a meter on everyone who claims this and not a one ever makes the fully charge necessary .


Only a couple dollars more for the right part .
