Not sure about 65 Marlins, but starting in 67 AMC used a "flasher" bulb for the parking brake on warning light. It wasn't a wedge base bulb but rather a regular miniature bayonet style with a small, round glass globe.
Maybe you have one of these in that position as I don't believe there's such a thing as a "main" instrument cluster bulb. |

If You have a voltage regulator on that year dash, I'd replace it.

The voltage regulator is bad. Any time both the fuel and temp gauge have the same faulty signs (both reading high or low, or not at all) that's most likely the case. Best replacement is a LM7805 electronic regulator. You can probably find an original type, but the electronic one is easy and reliable, and unseen. Edited by farna - Feb/12/2019 at 6:38am |

Looking at the back of the instrument cluster, the IVR is to the right and above the speedometer bulge. Hard to miss, it's a little metal rectangular piece. With the cluster mounted in the dash it would be on the driver's side of the speedo, but I don't think you can remove it with the cluster in. The Ambassador that year had the IVR built into the fuel gauge. That was surprising! I knew they put it in the fuel gauge on the Hornets and Gremlins, and late model Americans, but thought all the big cars (and up to mid 60s Americans) had a removable IVR. Marlin is Classic based in 65 and 66, only the 67 was Ambassador based.

Mine is just mounted to the board, no heat sink. I think TomJ's was like that too (it's his website). The little tab appear to be enough. I don't even know if the thing gets warm, all I can say is mine has been in there with no issues since 2003 and at least 70K miles, many of those on long trips between Gulfport MS and Lexington SC (8-9 hours) and Dover DE to Lexington SC (9-10 hours). I made those trips a couple times a year for six years when I was in the USAF -- it was my daily driver then. Got a truck shortly after I retired in 2007 and use it for work, hardly drive the Rambler in the last 6-7 years! Got to remedy that...
