About 15mins to solder in new switch if you remove old solenoid
Its amazing how TB's times are always 1 tenth of the actual time you take. Yes, it's only 15 mins to solder, but considerably more to dismantle the actuator gently to avoid damage. Nevertheless, it is a comparatively simple repair.
Remove boot, unclip loop. Punch out 2 pins. Separate black casing from white base (fiddly, but there is a knack, takes seconds). Sip tea, eat digestive. Less than a minute.
Desolder 3 connectors of switch, including a resistor. Switch falls out. Clip new switch in place, solder in, remembering to do resistor. Reassemble into black casing, and clip in place. Put loop and boot back on, knock 2 pins back in place. Sip more tea. Less than 5 mins.
Sit with a smug look knowing you've saved a small fortune, whilst finishing tea. 5 mins
All with help of Kevin Wood's excellent, clear guide
The hard, time consuming bits are removing the motor from door (15 mins if top of doorcard doesn't become detached), and about 25 mins to refit.
Personally, I always have a spare, so I can do the doorcard off, replace motor, doorcard on in one hit. Then refurb old one, and keep it for next time. There WILL be a next time with an Omega (not that Jag ones seem any better
)
