Many people are claiming for more light, and one way to get it, is to mount
a 80/90 or 90/100 W headlamp. However, it's not a matter of simply replacing
the lamp. There are some things, you better should do before. F.e., check
your bike for suitable relays (inside the dashboard), and if lacking, install
them. Obviously, TAs sold in Greek don't have relays for headlight operation.
If your bike is already equipped with relays, you probably should install thicker
cables (the green ones in diagram), and, maybe, bigger fuses.
Also, be sure to check your local laws, in some countries the use of
stronger headlamps is illegal!
Zervos Christos drew a wiring diagram, which I have posted here as a JPEG file (159 K). Originally it has been a PowerPoint document. When sending it, Zervos wrote:
Hello Deti,
I attach the powerpoint file which contains the electrical diagram on how to
wire a higher wattage headlamp (12V-100/90W) on a TA to replace the existing
(12V-60/55W) one. I tried to be as explanatory as possible. I have also
included (inside the powerpoint drawing) some "notes" which I consider
important and have to be taken in account before one proceeds to do that
headlamp "replacement". If you have any comments please let me know.
Of course some "disclaimers" have to be added, but you can use the same ones as
with all the other "how-to-do-it" instructions posted in your web site.
All '87-'96 TA models sold in UK (E), France (F), Spain (SP), Swiss (SW),
Austria (AR) and Italy (IT, IT-II) and all '96 TA models sold in Germany
(G, G-II) are NOT stock-equipped with headlamp relays and extra fuses. I do
not know about the after-96 models or the early US models.
The '91-'95 TA models sold in Germany (G, GII) appear to have stock-equipped
headlamp relays and extra fuses (2x10A). On those models, one could
possibly only upgrade the existing wiring (by thicker cables) and replace
the fuses (by 2x20A). BUT, headlamp main (high) current comes from the
fuse-box and not directly from the battery. So it would be much-much easier
to install new wiring and fuses (as per diagram) instead of upgrading the
existing wiring harness.
Disclaimer: I cannot be held responsible for any damage and/or mistakes made
when implementing this wiring circuit. If you're not going to install the
relays and the extra fuses, stick with stock 55/60w bulbs. Otherwise you run
the risk to burn your headlight switch and/or wiring harness. If you don't
install the extra fuses, your ran the risk of getitng fire in case of an
accidental short-circuit. If you're unsure of your wiring or electrical
skills, find a professional to help you. Safety comes first.
