I got a new rubber tube from ISP west. That will stop water. I think there
is a drain hole bottom of the lens.

 I tried the volt test off the fuse box on fuse 12, at idle it would drop
to 11.40 v. I have the vdo to the fuse box but through a relay of fuse 12
and the buzzer relay I removed. If I connect there then the voltage lamps
off idle in drive is the low 13.8 v.  Not sure why connected to fuse 12 the
voltage reads low. I also connected the the battery to calibrate the vdo
volt gauge. I know there is a voltage drop between the battery and fuse
box , this is why I used a relay. I will do further tests and once the part
shows up I will fix the water leak . I also ordered a new pair of headlamp
bulbs, mine are from 1985. I know how I have the voltmeter connected
through a relay offered a true reading and it,s all wired at the fuse box.
Spoke to others on samba and with no relay their readings are low.
