Headlight Relay - Searching

[Curt Sprenger]

Getting ready to install headlight relays...
I'm not finding a battery combiner. Anyone know where it might be
located on a 1987 PT38? I wonder if BB did not install one. I do find an
insulated terminal in the gen. compartment. That terminal has two
cables. One coming from way back in the coach, the other goes to the
gen. battery +. With the 8V92 running, or with the battery chargers, not
at the same time, that terminal tests about 14.4 volts. Remove the feed
and the terminal tests 13.8 and continues to decrease to lower volts.
Seems to me that terminal could be used to feed #30 on the headlight
relays.

Another option, maybe...
I opened up the front of the bus and find 2 open circuit breakers, 10A
each, 14.3 volts. The feed to that bus bar is at least a #10 wire and
could be a #8. The Silver Star headlights draw a little over 4 amps. Am
I safe using the 2 open circuits? I can replace the 10 amp circuit
breakers with 20 or 30 amp breakers.

Any and all input is appreciated.

Hi Curt,

I used the empty breakers you mentioned on my PT and on a friend's
FC. In both cases, I ran 10 ga. wire to each relay from the empty
breaker. If using standard Bosch relays, be sure to smear a ton of
silicone on the end where the connectors go (after attaching them).
Any moisture at all will ruin them- there can be no slits or
openings for the moisture to get in. I had two fail, even with
silcone, because I missed a few spots. Since sealing them up, no
problems.
