#Launch Tower Computer Electrical Diagnostic Test Procedures
This is for testing the electrical components and connections in the LTC.
##Initial Setup
(See Internal Routing image in [[Launch Tower Instructions]]
[[!table data="""

Disconnect: | R± | M± | S  | T  | Q± 
            | I± | J± | K± | L± | <-- all of these don’t connect devices like batteries and solar panel to the exterior connection
| N (to battery)| | | | O (to charger)
"""]]
S2 to “OFF”  


##Test Main Power Switch

S2 to “OFF”  
Continuity test across both H points  
[PASS] Have NO continuity across points  
[FAIL] Have continuity across points  

S2 to “ON”  
[PASS] Have continuity across points  
[FAIL] Have NO continuity across points  
S2 to “OFF”  


Test Solar Panel Connection and Lights
	
S2 to “OFF”  
Connect 9-16VDC (VINPUT) to J±  
[PASS] L1 light is ON  
[FAIL] L1 light is OFF  

Depress and hold S1  
[PASS] L1 light is OFF  
[FAIL] L1 light is ON  
S2 to “OFF”  



##Test System Battery Connection and Lights

S2 to “OFF”  
Connect 9-16VDC (VINPUT) to I± or L±  
[PASS] L2 light is ON  
[FAIL] L2 light is OFF  
S2 to “OFF”  

S2 to “ON”  
[PASS] L3 and L4 and L5 light is ON   
[FAIL] L3 and L4 and L5 light is OFF  
S2 to “OFF”  


##Test Power Conversion

S2 to “OFF”  
Connect 9-16VDC (VINPUT) to I± or L±  
S2 to “ON”  
Voltage Check: A± B± C± D± E± F±   
[[!table data="""
| A± and B± | C± and D± | E± and F±
[PASS] | (VINPUT) ± .02V | 5V ± .02V | 24V ± .02V
[FAIL] | != PASS | != PASS | != PASS
"""]]

S2 to “OFF”


##Test Phidget Board

S2 to “OFF”  
Connect: M±  
S2 to “ON”  
Voltage Check: M±  
[PASS] Voltage = (VINPUT) ± .02V  
[FAIL] Voltage ! = (VINPUT) ± .02V  
Note: Ok if L5 goes out. This indicates Phidget board has turned off 24v converter.  
S2 to “OFF”  

##Test Ignition Board

###Board Power
S2 to “OFF”  
Connect: Q±  
S2 to “ON”  
Voltage Check: Q±  
[PASS] Voltage = 5V ± .02V and L6 is ON  
[FAIL] Voltage != 5V ± .02V or L6 is OFF  
S2 to “OFF”  

###Shore Power
Disconnect: M±  
Connect: R+  
S2 to “ON”  
Voltage Check: R+ / Q-  
[PASS] Voltage = 24V ± .02V and L5 is ON  
[FAIL] Voltage != 24V ± .02V or L5 is OFF  
S2 to “OFF”  
Re-Connect: M±  
###Ignition Battery

NEED PROCEDURE HERE



##Test Ignition Battery Charger

S2 to “OFF”  
S2 to “ON”  
Voltage Check: S (positive tip)  
[PASS] Voltage = (VINPUT) ± .02V  
[FAIL] Voltage != (VINPUT) ± .02V  
Connect: S  
[PASS] Battery charger turns on  
[FAIL] Battery charger does NOT turn on  

Note: If charger display shows “Er2” – it indicates the input voltage on S is greater than the 16V maximum input of charger.  
S2 to “OFF”  

##Test Beagleboard
S2 to “OFF”  
S2 to “ON”  
Voltage Check: T (positive tip)  
[PASS] Voltage = 5V ± .02V  
[FAIL] Voltage != 5V ± .02V  
Connect: T  
[PASS] L7 is ON and L8 and L9 start flashing  
[FAIL] L7 is OFF or L7 is RED  

Note: Failure at this stage may indicate the polarity is revered on connection

Note: At this stage it may not be a good idea to turn S2 to “OFF” because it could corrupt the beagleboard image. Instead, let computer boot – connect to it and power down the board normally.
S2 to “OFF”
