I-Mark & Impulse
Using ohmmeter, check resistances across lettered terminals as listed in chart. SeeFig 1 . If resistances are not correct, replace gauge.
TEMPERATURE GAUGE RESISTANCES - I-MARK
| Terminal Position | Ohms |
|---|---|
| IG-U | 90 |
| IG-E | 248 |
| U-E | 158 |
TEMPERATURE GAUGE RESISTANCES - IMPULSE
| Terminal Position | Ohms |
|---|---|
| IG-U | 88 |
| IG-E | 197 |
| U-E | 109 |
