Re: [MBZ] Suddenly dead cluster lights - 1985 W123
Bad ground or a crack in the trace on the cluster. Don't remember if that's the same rheostat as the W108/W116, in which case it's probably easier to jumper it when it goes bad, no longer available if it's too corroded to work anymore. Peter Same. Same on 110/111/112/113 also. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

IIRC some deoxit applied to the rheostat worked well to correct this on mine.

Re: [MBZ] Suddenly dead cluster lights - 1985 W123
Corrosion in the rheostat. I soldered a jumper to bypass the dimmer, since the bubs are pretty dim anyway. The dash lights (including all instrument cluster gauges and ACC control panel) on my 1985 300TD quit working when I took the car for a spin after it had sat idle for a couple weeks. The radio lights continue to work, however. I fiddled with the dimmer control know but nothing changed, and the lights did NOT come on briefly/intermittently while i was twisting the knob back and forth. Other than the rheostat, could anything else be causing these symptoms? ___ ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] Suddenly dead cluster lights - 1985 W123
Twiddle the rheostat a bunch, I've had them seem completely dead for a surprisingly long period of time before they came back. If that doesn't help try pushing the cluster around a little, could be a bad ground but that should make the temp rise erroniously and the fuel gauge pulse with the clock... -Curt From: Andrew Strasfogel via Mercedes To: Mercedes Discussion List Cc: Andrew Strasfogel Sent: Monday, November 16, 2015 2:57 PM Subject: [MBZ] Suddenly dead cluster lights - 1985 W123 The dash lights (including all instrument cluster gauges and ACC control panel) on my 1985 300TD quit working when I took the car for a spin after it had sat idle for a couple weeks.
