Electric problems

[DeanG]

Any help appreciated I'm putting a 1990 Seven back on the road after being off the road for 15 years everything seems to be working accept indicators,hazards and horn all working off the relays not sure if I've missed a connection somewhere thanks for any help 

[Jonathan Kay]

Do you have a multimeter?

And the appropriate wiring diagrams? Let me know if you'd like them. 

Jonathan

Thank for reply I have a multimeter I've checked the fuses and the relays have a live feed it seems strange that all relays are not working also not sure what replacement relays needed as there are no markings on them 

[Jonathan Kay]

You can probably find replacement relays by asking Redline or taking yours into Halfords or similar and matching by eye.

And I'll check to see if I have part numbers.

Have you established the relay layout?

Jonathan

[DeanG]

I will try them  thanks I have the original layout and diagram but just not that clear

[Tony P]

Do you have the ignition key in the 'fully on' position?
(It's something that's tripped me up in the past.)

[DeanG]

Yes tried that thanks I'm going to order all new relays I don't think it's that but just to eliminate that

Does this car have the resettable circuit breakers on the scuttle forward side, left hand side, My 1982 car has these and they are not very reliable, mainly due to poor connections between the socket on the panel and the pins in the resettable fuse unit get loose, if this is you try and close the sockets in the fixed panel mounted item, so better contact is made with the pins, and make sure the reset button is not tripped, just give it a push, it doesn't seem too change position from one state to the other, If your car doesn't have these you won't need all this guff.

Have fun. Nigel.

Rather than trying to fix everything in one fell swoop, carefully trace and test one (1) circuit until you find the issue.  Do not randomly change relays and switches hoping to luck upon the solution.

Multimeters are great tools, especially for testing continuity.  Unfortunately, digital voltmeters have very, very high impedance and will show battery voltage in a circuit that couldn't light a 0.2w bulb.  Get a test light with an incandescent bulb.  This applies a light load to the circuit and is much better at finding poor connections.
