Electrical system fun!

Years ago I built an MG-TD kit car on a VW frame. The assembly was fairly easy, but the electrical system was just too much. I got her running and went to an auto-electric company for finishing. I am simply not skilled with a wiring harness and my current MGB has just developed an illness which I would like some opinions on before I get to work on it or turn her over to the shop. Yesterday while crusing along I noticed that the directional signals had stopped working. They do not light or flash. This was fairly sudden since they had worked at a turn 2 miles previous. I then noticed that the tachometer, the heat guage and fuel guage had pooped out as well. I had problems with the fuel guage about a month back which I "cured" by cleaning and greasing the contact at the sending unit. I tried this again but no joy. I checked the hazard flash and the bulbs function properly so I know they are OK. Headlights are OK as well. I am thinking to start by checking the fuses and then on to the mare's nest of wires that reside under the dash. Any ideas?
Thanks,
Mike
 
I would check the green wires at the fuse box. If it was just the signals then go to the emergency flasher switch. But you seem to have a green circuit problem. Happy hunting, Bob
 
Thanks for the help Bob. 10 minutes, an emery file, dielectric grease & VOILA!
Everything working great again. Thanks again. You have saved me from much aggravation and more than a few dollars at the shop.
Cheers,
Mike
 
Mike, Are you going to the show in Columbia SC this sunday? Lynda and i are planning to show up and look around. We are going to take Lynda's 63 iris blue MGB. We are planning a trip to western Mass. in 2 weeks and need to give it a shake down run. bob
 
Bob,
No I won't be there. I am always a bit wary about running "Ms. B" too far afield. I am sure she would do well, but for now I'm content to stay local. Then there is the issue of Church, since I am a Catholic Deacon I have to assist at morning Mass. I would not be able be there much before 3:00 PM in any case. If you and the wife decide to come play tourist in Charleston, please let me know. If you do Sherrie and I would love to show you around.
Cheers,
Mike
