Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Revs not going to idle

According to Laurens last post above he has thoroughly checked out speed sensor and associated wiring and connectors. Note he reports the speedo works correctly and TSM cancels the indicators when moving. The ECU is obviously receiving something as well since the idle problem dissapears when he disconnects the speed sensor. This of course interrupts the speedo reading, hence my suggestion of just disconnecting the ECU speed feed as a temporary measure where there is a three way split at a bombtail.

BTW please note this present discussion relates to pre-2014 M3W's. Among others there are many differences to the TSM on the later models most notable being the integral indicator relay and a different connector with more pinouts. Main loom is obviously different to accommodate, plus of course cooling fan, heated seats and likely many more minor changes.
