My starter motors run on 24v and all my instruments have died or are well out of date . Can I replace with 12v intruments with out any detrimental effects.My internal boat power supply is 12V.

I do have 2 sperate charging systems. The 24v only starts both engines and one engine supports a 24v alternator always started first.The reason I am thinkling of going 12v is I am changing the sensors on the engines from cappilary to electric and the 12 v sensors and supporting instruments seem to be cheaper
As was mentioned earlier , many modern instruments run on 9v to 32 v but , for example , Raymarine ST50 instruments are 12V only.
BlueLancer - are you looking to replace sailing instruments or engine instruments?
Given the reference to starters I thought it was the latter, hence my earlier question.
If it is sailing instruments then it should be much easier to keep the 12V circuits separate from the 24V (engine only) circuits.
Engine intruments are what I am replacing The originals have died and the oil pressure gauges are capillary, which I wish to change to electric.I thought it would be easier to go 12v, as I have to rewire the engines anyway.
Does the 24V circuit power anything other than the starters - keyswitch, relays, glow plugs etc. ?
