3 problems with my clocks? can you help ?

1st problem the buzzer in the clocks starts buzzing after twenty mins at 3000 revs upwards then goes when car cools down a bit but the temp warning light works good ??

2nd problem my high beem led light is very dim but works??

3rd problem rev counter needle just drops to 0 somtimes rarely but with a bang from the hand to the dash it somtimes cures it?

good hey  

any opinions people of earth? or simple cures?

i know how to take the clocks out and disamble it just not great with wires i have a current tester, the one that has a little bulb in it only

thanks for reading

1. check high pressure oil switch in filter housing, and wire to it. make sure oil pressure is ok. might be related to 3 though
2. change the bulb
3. dash problem or loose connection on the plug to it, could be related to 1

how do i check the oil switch itself  , what faults am i looking for jonny man? does the wire run all the way up to the clocks? how can i test the wire?

switch is just an on/off switch so can check with a multimeter. wiring you could try earthing and leaving wire off see if that effects dash buzzer at all. wire runs from sender to fusebox, then fusebox to dash see the faq

bloddy hate car electrics thanks.

Took the clock apart and found a blown bulb for problem 2 well done!! do you know where i can get more from???  

I was in the middle of putting some tappets in today and found the the rocker cover i put in a month ago was two wide though the right one and had crumbled off all around the inside!!!!!!!!!!!  Jesus i said, so now im thinking the shit has cloged up the oil filter and is restricting oil flow and pressure!!!!!!!! i only put good oil in it october maybe i could strain it ????and just replace the filter ? I recon i might of sussed out problem 1 i dont know it seems very likley to me.

i stripped some mk2 clocks and pinched the bulb for mine, converted it from yellow to blue at the same time

you're going to have to have the sump off at least, if you're lucky those bits of gasket are in the pickup and no stuck in the engine somewhere
