10 A V OL TA GE BEFORE AND AFTER C ONT ACT VOL TA GE BEFORE CONT ACT A constant voltage is supplied to pin 1 of connector 416 through wire 1008, point 30 on the starter motor ,fuse E286, the + bolt in the dashboard connector lead-through and the voltage distribution block. Power is also supplied (via w ire 1008) from point 30 of the starter motor to the B+ connection of the alternator and to relay G 014 (glow-plug relay). Power is supplied to the “S” (sens) connection of the alternator from point 30 of the starter motor via fuse E279 and wire 3084. Only wire 1008 to the + bolt in the dashboard connector lead-through is fuse-protected by fuse E286 (125A). The other wires are NOT fuse-protected and they can only be m ade dead by disconnecting the battery leads.. VOL TA GE AFTER C ONT ACT A voltage is supplied to contact relay G015 (connection point 30) via the starter m otor (connection point 30). T his connection point may be connected to w ire 1010 over contact relay G 015. This wire is only fuse-protected w ith fuse E286 (125A). OPERA T ION When the accessories/ignition/starter switch (C539) is set to the “accessories” position (connection between points 1 and 6), a voltage is supplied to connection point 1 of relay G 377 via w ire 1000, fuse E037, accessories/ignition/starter switch (C539) (contact points 1 - 6) and wire 1130. When the accessories/ignition/starter switch (C539) is set to the “contact” position (connection between points 1 and 4), relay G015 is energised via wire 1000, fuse E037, accessories/ignition/starter switch (C539) (contact points 1 - 4) and wire 4001, relay G015. This then connects wire 1000 (voltage before contact) to wire 1010 (voltage after contact). At the same m oment this voltage is also applied to connection point 85 of relay G 426. This relay is also activated and connects contacts 30 and 87. A voltage is now applied both to fuse E 350 and to fuse E351 via fuse E037, contacts 30 - 87 and wire 1234. The voltage goes to connection point 15 of the alternator via fuse E 350. When the accessories/ignition/starter switch (C539) is turned against the pressure of the spring (connection between points 1 and 2), relay G 015 and relay G 426 remain energised and a volt age is supplied to the alarm syst em (D91 1) (if present) or directly to connector 403, connection point 2, via w ire 1000, fuse E037, accessories/ignition/starter switch (C539), contacts 1 - 2 and wire 4004. When the ignition/starter key is released, the ignition/starter switch automatically springs back and remains in the “contact” position. 200404 2-24 5 ELECTRICAL SYSTEM Electrical system CF65/75/85 series ≥0E621376 |
