    If you're only using Vactan with no blacking over the top it makes for an easier job and it will also be easier to prep and recoat next time. However, don't expect a water based coating to last very long in a water tank.

    Could I paint tank black on top of vactan? 

  2. I'm just about to clean out my water tank and re paint,I had tank blacking on before,but this time I'm  going to use vactan for the first time, and not but any tank black on,I'm just going wire brush any flaky paint from before and coat it in vactan.

    No, I did not sorry. Still the advice I gave to IanMC hold good for him and as for Jddevel I await more info. What I said to him may or may not be good advice.

    I wish people would not confuse the issues in this way. All it will take is starting the post by something like "I have another problem and it seem this is a good pace to ask about it" if the post has to go into the topic. Better still start another one because that keeps all the info for ONE problem in one place and runs no risk of confusing the issue.

    Thanks for the advise,and I'm sorry for confusion.

    The problem is that larger alternators cannot really be driven by a standard V belt as the belt isn't capable of transferring that much power - it will slip. 110A is on the cusp of that and is probably a bit too much although it depends on the size of the pulleys. Perhaps it would be better to make sure you are getting the best out of the 70A alternator. In other words, that it is working properly (no blown diodes reducing output), that the wiring is transferring the current to the batteries without dropping much voltage and that you are running the engine fast enough to spin the alternator fast enough to produce its full output. If all those are good you could consider an alternator controller such as an Adverc or a Sterling A2B

    Electricity is invisible and so you need adequate monitoring equipment, do you have some sort of battery monitor, or at least a multimeter, preferably a DC clamp meter? Without some monitoring equipment, you are working in the dark.

    I'm not doing the work I've got this guy who says I need a bigger amp alternator I've no idea about electrics,I don't want to throw lots of money at this as I might be wasting my time,I've had the boat rewired,I've only got lights and pumps running off 2 leisure batteries and 1 engine starter battery running from a 70amp alternator I'm sure this would be ok,but this guy seams to think I need more power.
