I have seen this question posted a lot on many boating boards but I am not sure that my situation is the same as others that I have read. I have a 2005 Volvo 5.7 Gi Sx outdrive and cannot get the trim/tilt to work. I have shotgunned several things with no positive results. The DC motor has been changed, the up down solenoids have been changed and I have started to run checks on voltage. I have +- 12 volts coming up the line to the motor and get solid clicks from solenoids in both directions with the motor disconnected. As soon as the motor is connected or anything requiring a load (multimeter) is connected there is a rapid clicking from the solenoids and there is static over the radio speakers. At this point I am thinking that there may be two issues at work here; 1. not enough power to keep the solenoids closed or 2. the grounding is bad. The problem is that I really don't know how to check either of those items. Suggestions ... or am I going down the wrong path??
