Following my experiences in early December, I hurriedly tried to get a replacement glow plug (seven flashes on the panel) prompting me. After failing to purchase a spare fom my nearest Bosch listed stockist (which has apparently been a Chinese Takeaway for the last four years). To get a spare in time for the Christmas Cruise (which we weren't able to make because of family illness) I ordered one through a friend who is a garage owner — the cost of this part turned out to be £10 more than ex Mikuney (chuckles regarding yet another example of my non-money saving purchasing strategy from his former worship), the guy showed my the invoice from his supplier, so he wasn't ripping me off. Anyway, I was at last able to get to the boat yesterday, and then following Julian's excellent instructions I was able to remove the old glow plug, do a continuity test (which indicated no fault) clean the air holes in the plug boss reinsert the old glowplug and fire up the central heating and have lunch in less time (including the 65 mile journey to the boat) in less time than it took me to go nine miles on the previous aborted attempt to go boating last Thursday. Thanks Julian and Roger for your help and advice, I now know what to do when the glow plug eventually fails, and I now have a spare, which I needed anyway. One small point, after being advised to set the system so that the heater doesn't keep cutting in and out, I turned off the radiator nearest the thermostat, and after about 1.5 hours continuous running, the d***n thing started to boil. Should this happen? There are four large radiators, the Squirrel back boiler (Squirrel not lit yesterday) and a 22mm by-pass pipe in the circuit, all radiators (except the aforementioned one) were on and the bypass and Squirrel circuit 50% open. Any comments? Regards ........................... Arthur Naylor
