Need better Kenwood KR-5030 Schematic due to Weird FM light / LED kit doesn't work issue

Anyone has a Kenwood 5030 high resolution scan file? The online scans are not up to snuff.

The issue. FM indicator light out. Bought Joe's replacement LEDs. They got hot. Checked voltages. 47v with bulb out of circuit. 9.6v bulb in circuit. Should be 8v. Receiver plays fine and swapping original Kenwood incandescent bulbs, the bulb seems fine with the higher voltage.
Do incadescent bulbs act differently in circuit?

I posted this on another KR-5030 thread but i will post the same here since you had the same issue. Did you find the answer? I ordered a set of leds from ebay that were supposed to fit the KR=5030 and they lit up for awhile and quit. I got the same voltage readings you got so I assume leds will not last with that much voltage. I am working on a KR-5330 which is the same as a KR-5030 but with a dark colored face plate.
 
I found a 8v 50ma incandescent lamp that i put in place of one of the ebay diodes and it lights up, stays cool and shows 8v instead of the 47v. I guess just because Ebay says it will work I should have researched it further before I ordered them. Hope this helps someone else in the future.

I think the bulbs are in series to lower their I overall voltage. In any case I now approach LEDs with caution. I am get better pricing from AliExpress and Temu for 8v LEDs.
