Note On Intermittents
If an intermittent condition exists, check B410 snap data parameters BD61 and BI51. Also check for following conditions:
- If BD61 is less than 500 RPM and BI51 is high, check for an intermittent open in circuit No. 25.
- If BD61 is less than 500 RPM and BI51 is low, check for an intermittent short to ground in circuit No. 23.
- If BD61 is greater than 500 RPM and BI51 is high, check for an intermittent short to ground in circuit No. 23.
- If BD61 is greater than 500 RPM and BI51 is low, check for an intermittent short to ground in circuit No. 25. Fig 2 .
