Where do I start lookin?

Thanks in advance

mythplaced,

There is a SmartWheel troubleshooting document at the Alpine Coach Association technical document site:

http://alpinecoachassociation.com/ch...ng%20Guide.pdf

On page 3, you will see the following which indicates relays that you might want to check (I don't know where the relays are, but you could check under the dash).

CRUISE FUNCTIONS:
Because of the requirement that the cruise control functions be extremely flexible to accommodate
the various brands of cruise control systems, the Smart Wheel System incorporates four individual
relays with the normally-open and normally-closed contacts available to those systems. It also
incorporates a programmable jumper field (JP1) that allows the common (armature) contact of the
Cruise On/Off relay to be connected to one of three sources. If the jumper on JP1 is placed in
position "A", the common contact on the Cruise On/Off relay will be connected to the Cruise
Common input (J11.5). If the jumper on JP1 is placed in position "B", the common contact on the
Cruise On/Off relay will be connected to the Ignition input (J2.4). If the jumper on JP1 is placed in
position "C", the common contact on the Cruise On/Off relay will be connected to ground. In order
to insure proper operation of the cruise control system the technician should consult with the
chassis manufacturer to determine the proper jumper setting prior to installing or replacing a
Master. In accordance with many of the cruise control system manufacturer's requirements, these
relays are "dry-circuit" rated with gold plated contacts rated at 1 Amp max. at 12Vdc.

CRUISE ON - Operation of this switch latches the Cruise On/Off relay in the "on" state. This
causes the source determined by the jumper position on JP1 to be disconnected from the Cruise
On/Off normally-closed

CRUISE OFF - Operation of this switch unlatches the Cruise On/Off relay. This causes the source
determined by the jumper position on JP1 to be connected to the Cruise On/Off normally-closed
(N.C.) output (J11.7) and disconnected from the Cruise On/Off normally-open (N.O.) output (J11.8).
In essence, this function is inverse to the Cruise On function. This mode is also entered any time
that +12Vdc power is removed from the Ignition input (J2.4) on the Master.

CRUISE SET - Operation of this switch operates the Cruise Set relay while the switch is pressed.
This causes the Cruise Common input (J11.5) to be disconnected from the Cruise Set normallyclosed
(N.C.) output (J11.2) and be connected to the Cruise Set normally-open (N.O.) output
(J11.2).

CRUISE RESUME - Operation of this switch operates the Cruise Resume relay while the switch is
pressed. This causes the Cruise Common input (J11.5) to be disconnected from the Cruise
Resume normally-closed (N.C.) output (J11.4) and be connected to the Cruise Resume normallyopen
(N.O.) output (J11.3).

CRUISE CANCEL - Operation of this switch operates the Cruise Resume relay while the switch is
pressed. This causes the Cruise Cancel Common input (J11.9) to be disconnected from the Cruise
Cancel normally-closed (N.C.) output (J11.10) and be connected to the Cruise Cancel normallyopen
(N.O.) output (J11.11).

The relays (brain box) for the smart wheel is located to the left of the steering column, screwed to in inside firewall. Very difficult to see. Box is approx. 8"x8" with 5 or 6 plug in connectors and two wire connectors. Relay boxes are specific to steering wheel types and series. Mine is a 209 series and will use a 209 box or 210 series. there is also a fuse located there.
Another easy check to see if relays are working is to turn on ignition and press steering wheel buttons and listen for the relays to click. Per VIP smart wheel tech if fuse is good, and cruise fuse in chassis fuse block is good, and the relays click, smart wheel controls are most likely ok. Then you may have to look at the cruise control circuit at engine. Pm me for more info on smart wheel box is you wish

Thanks!

I know where the house fuse block is....but where is the chassis fuse block?

Most of the chassis fuses are in front of the passenger seat. A few, oddly, remain at the batteries. Your electrical chart should show them (available on ACA website).
