Location of Fuse for lights

[tom winslow]

My front lights over the cab are out. The rear are Ok. Only the front.

Is there a separate fuse for these lights?

The clearance lights on the front still do not work.

Tonight we went to K-mart and picked up an 'Under-the-Counter' coffee maker,
B&D. Also, got a volt-ohm meter. Checked all the fuses and all are OK.

If I have a bad ground, and that seems logical, do I look for a single
ground. Any suggestions as to what procedure to follow? I looked in the
maintenance manual for '74-'75 but did not get much help. I would like to
get these lights running because the wife wants me to take her to Myrtle
Beach Friday night for the weekend.

No separate fuse that I know of. Probably a bad ground if all are out.

I would first check for 12 volts in the socket... maybe you did, already.
Change to the 12 volt range first, and then then see if you get 12 volts
between the 2 contacts in the socket. If not run a several foot length
of wire between a good ground like the outside chrome shell of the cigar
lighter and one of the metal screws of the light fixture. Just hold the
wire on the metal, and see if the light switches on. If there is light,
you have a bad ground (probably in the light socket or the connection
from the socket to the metal frame). (you did check to see if the bulb
was good)? The bulb should read almost a dead short on the ohms
scale. (really about 1-2 ohms) If still no luck you have a bad switch.

HI Tom, Check the GROUND. f you open the lens with screw, you probably
should put some clear silicone on the edge when you close the lens to the
light. I put silicone on the wire hole as well to ensure moistur does not
go into the roof cap area. Chuck

Tom...

I just re-read your original message, and realized you said the front
clearance lights.

I thought (for some strange reason) you were haveing trouble with the
front cockpit eyeball lights. I had a bad ground there once, I recall
now.

The procedure is the same but you can probably find a more convenient
ground to run the test ground wire to. Also use a good ground point on
the socket of the clearance light, as the screw on that fixture may not
be a ground, like the screw on the eyeball fixture is.

Easiest way to check for the problem is to run a wire from the negative side
of the battery long enough to reach the lights. With the voltmeter place the
black probe on the wire and the red probe in the center of the light (after
you remove the bulb). If you get 12V than you have a bad ground somewhere on
the lights. If you don't get 12V than you have a problem in getting 12V to
the lights. do you have an electrical diagram for the coach?
