Component Testing

Relay Test

1. Ignition OFF, disconnect the appropriate K149 Folding Top Pump Motor Relay.
2. Test for 85 - 105 Ω between terminals 85 and 86.
   • If less than 85 Ω or greater than 105 Ω 

     Replace the K149 Folding Top Pump Motor Relay.

   • Go to next step: If between 85 - 105 Ω 
3. Test for infinite resistance between the terminals listed below:
   • 30 and 86
   • 30 and 87
   • 30 and 85
   • 85 and 87
   • If less than infinite resistance 

     Replace the K149 Folding Top Pump Motor Relay.

   • Go to next step: If infinite resistance 
4. Test for less than 2 Ω between terminals 30 and 87A.
   • If 2 Ω or greater 

     Replace the K149 Folding Top Pump Motor Relay.

   • Go to next step: If less than 2 Ω 
5. Install a 3 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground.
6. Test for less than 2 Ω between terminals 30 and 87.
   • If 2 Ω or greater 

     Replace the K149 Folding Top Pump Motor Relay.

   • Go to next step: If less than 2 Ω 
7. All OK

Motor Static Test

1. Ignition OFF, disconnect the harness connector at the M23 Folding Top Pump Motor.
2. Test for 78 - 117 Ω between the control circuit terminal 1 and the signal circuit terminal 2.
   • If not between 78 - 117 Ω 

     Replace the M23 Folding Top Pump Motor.

   • Go to next step: If between 78 - 117 Ω 
3. Test for infinite resistance between each terminal and the sensor housing/case.
   • If less than infinite resistance 

     Replace the M23 Folding Top Pump Motor.

   • Go to next step: If infinite resistance 
4. All OK

Motor Dynamic Test

1. Install a 10 A fused jumper wire between the control terminal 2 and 12 V.
2. Momentarily install a jumper wire between the control terminal 1 and ground. The M23 Folding Top Pump Motor should operate.
   • If the pump motor does not work 

     Replace the M23 Folding Top Pump Motor.

   • Go to next step: If the pump motor works 
3. All OK
