Paul,
Since the early Ambos used the key switch to directly control the
current to the solenoid of the starter you will have to make a few
changes. First you will need a relay. The solenoid of the Valeo starter
has about 1 ohm of resistance, which means that it will draw about 12
amps when you energize the starter. In order to get a relay to last when
used with an inductive load it must have a resistive load rating of at
least twice the required current. This means that for your application
you must have a relay rated 25 amps or more unless you want to buy them
by the gross.
Bosch makes several relays which would work. Their part numbers and
descriptions are:
332 019 110 SPST 40A 12V with mounting bracket, 332 209 151 same rating
no bracket, 332 209 150 SPDT 40A 12V w/brkt, 332 019 151 SPDT 40A 12V no
brkt, 332 209 137 SPDT 50A(!) 12V no brkt. If you can't find a genuine
Bosch relay just ask for an auxilliary headlight (driving light) relay.
You will also want to pick up some female 1/4" quick disconnect
terminals, unless you get lucky and the auto parts store has a prewired
harness for the relay.
Reroute the wire going to the solenoid to the new relay and connect it
to terminal 85 on the relay. Connect terminal 86 via a piece of 16 or 18
(larger is OK)gauge wire from the relay to a good ground point on the
bike (Buy a 5/16 or 3/8 ring lug to get the wire landed under a bolt or
nut). Get an inline fuse holder and wire a 25 amp fuse (using 12 or 14
gauge wire) between the positive terminal of the battery (connect this
LAST!!!) and terminal 30 of the relay. Connect a piece of wire from
terminal 87 of the relay to the new starter solenoid (on the quick
disconnect terminal).
The hardest part of the job will probably be rounding up all the parts.

| John, I looked thru guzziology and found what I was looking for. Thanks. I started today on getting it fitted. I followed Tom Bowes suggestion on grinding off the small vertical plate by the upper mount ( Gee it's great to have a Dremel for this type of work). I also drilled out the threads on this mount so I could push the bolt thru and tighten it all up. I had to paint the starter where I removed the vertical plate so it looks like nothing was ever modified. Looks real good. I will take some pictures of everything I have done so if anyone else wants to see they can see how I did it. The only thing I still have to do is wire up the relay, but I want to make sure on what relay I need for this. Paul 69 Ambo with partially fitted Valeo |
