A member reported that their 1998 Sun Voyager started, then was shut off after a red gear-shaped warning light with an exclamation point appeared, and now it will not start again. Members suggested checking for diagnostic codes with an OBD-II reader if compatible with the chassis, though one RVer noted a code reader may not work on a similar late-1990s Gulfstream.
Other suggestions included disconnecting the negative battery cable briefly to attempt a reset, checking the transmission fluid, and, if it is a diesel that cranks but does not start, considering a fuel filter issue or lost fuel prime. The discussion did not reach a confirmed diagnosis or repair.
